W83697HF/F
GENERAL DESCRIPTION
The W83697HF is evolving product from Winbond's most popular I/O family. They feature a whole new
interface, namely LPC (Low Pin Count) interface, which will be supported in the new generation chip-set.
This interface as its name suggests is to provide an economical implementation of I/O's interface with lower
pin count and still maintains equivalent performance as its ISA interface counterpart. Approximately 40 pin
counts are saved in LPC I/O comparing to ISA implementation. With this additional freedom, we can
implement more devices on a single chip as demonstrated in W83697HF's integration of Game Port and
MIDI Port. It is fully transparent in terms of software which means no BIOS or device driver update is needed
except chip-specific configuration.
The disk drive adapter functions of W83697HF include a floppy disk drive controller compatible with the
industry standard 82077/ 765, data separator, write pre-compensation circuit, decode logic, data rate
selection, clock generator, drive interface control logic, and interrupt and DMA logic. The wide range of
functions integrated onto the W83697HF greatly reduces the number of components required for interfacing
with floppy disk drives. The W83697HF supports four 360K, 720K, 1.2M, 1.44M, or 2.88M disk drives and
data transfer rates of 250 Kb/s, 300 Kb/s, 500 Kb/s,1 Mb/s, and 2 Mb/s.
The W83697HF provides two high-speed serial communication ports (UARTs), one of which supports serial
Infrared communication. Each UART includes a 16-byte send/receive FIFO, a programmable baud rate
generator, complete modem control capability, and a processor interrupt system. Both UARTs provide
legacy speed with baud rate up to 115.2k bps and also advanced speed with baud rates of 230k, 460k, or
921k bps which support higher speed modems. In addition, the W83697HF provides IR functions: IrDA 1.0
(SIR for 1.152K bps) and TV remote IR (Consumer IR, supporting NEC, RC-5, extended RC-5, and RECS80 protocols).
The W83697HF supports one PC-compatible printer port (SPP), Bi-directional Printer port (BPP) and also
Enhanced Parallel Port (EPP) and Extended Capabilities Port (ECP). Through the printer port interface pins,
also available are: Extension FDD Mode and Extension 2FDD Mode allowing one or two external floppy disk
drives to be connected.
The configuration registers support mode selection, function enable/disable, and power down function
selection. Furthermore, the configurable PnP features are compatible with the plug-and-play feature demand
of Windows 95/98
TM
, which makes system resource allocation more efficient than ever.
The W83697HF provides a set of flexible I/O control functions to the system designer through a set of
General Purpose I/O ports. These GPIO ports may serve as simple I/O or may be individually configured to
provide a predefined alternate function. General Purpose Port 1 is designed to be functional even in power
down mode (VCC is off).
The W83697HF is made to fully comply with Microsoft PC98 and PC99 Hardware Design Guide, and
meet the requirements of ACPI.
The W83697HF contains a game port and a MIDI port. The game port is designed to support 2 joysticks and
can be applied to all standard PC game control devices, They are very important for a entertainment or
consumer computer.

W83697HF
The W83697HF provides Flash ROM interface. That can support up to 4M legacy flash ROM.
The W83697HF support hardware status monitoring for personal computers. It can be used to monitor
several critical hardware parameters of the system, including power supply voltages, fan speeds, and
temperatures, which are very important for a high-end computer system to work stably and properly.
Moreover, W83697HF support the Smart Fan control system, including the “Thermal CruiseTM” and “Speed
CruiseTM” functions. Smart Fan can make system more stable and user friendly.

2. LPC (LOW PIN COUNT) INTERFACE
LPC interface is to replace ISA interface serving as a bus interface between host (chip-set) and peripheral
(Winbond I/O). Data transfer on the LPC bus are serialized over a 4 bit bus. The general characteristics of
the interface implemented in Winbond LPC I/O are:
•
One control line, namely LFRAME#, which is used by the host to start or stop transfers. No peripherals
drive this signal.
•
The LAD[3:0] bus, which communicates information serially. The information conveyed are cycle type,
cycle direction, chip selection, address, data, and wait states.
•
MR (master reset) of Winbond ISA I/O is replaced with a active low reset signal, namely LRESET#, in
Winbond LPC I/O.
•
An additional 33 MHz PCI clock is needed in Winbond LPC I/O for synchronization.
•
DMA requests are issued through LDRQ#.
•
Interrupt requests are issued through SERIRQ.
•
Power management events are issued through PME#.
Comparing to its ISA counterpart, LPC implementation saves up to 40 pin counts free for integrating more
devices on a single chip.
The transition from ISA to LPC is transparent in terms of software which means no BIOS or device driver
update is needed except chip-specific configuration.

3. FDC FUNCTIONAL DESCRIPTION
3.1
W83697HF FDC
The floppy disk controller of the W83697HF integrates all of the logic required for floppy disk control.
The FDC implements a PC/AT or PS/2 solution. All programmable options default to compatible
values. The FIFO provides better system performance in multi-master systems. The digital data
separator supports up to 2 M bits/sec data rate.
The FDC includes the following blocks: AT interface, Precompensation, Data Rate Selection, Digital
Data Separator, FIFO , and FDC Core.
3.1.1 AT interface
The interface consists of the standard asynchronous signals: RD# , WR#, A0-A3, IRQ, DMA control, and
a data bus. The address lines select between the configuration registers, the FIFO and control/status
registers. This interface can be switched between PC/AT, Model 30, or PS/2 normal modes. The PS/2
register sets are a superset of the registers found in a PC/AT.
3.1.2 FIFO (Data)
The FIFO is 16 bytes in size and has programmable threshold values. All command parameter
information and disk data transfers go through the FIFO. Data transfers are governed by the RQM and
DIO bits in the Main Status Register.
The FIFO defaults to disabled mode after any form of reset. This maintains PC/AT hardware
compatibility. The default values can be changed through the CONFIGURE command. The advantage of
the FIFO is that it allows the system a larger DMA latency without causing disk errors. The following
tables give several examples of the delays with a FIFO. The data are based upon the following formula:
THRESHOLD # × (1/DATA/RATE) *8 - 1.5 µS = DELAY
FIFO THRESHOLD
MAXIMUM DELAY TO SERVICING AT 500K BPS

8 × 16 µS - 1.5 µS = 6.5 µS

Revision 0.70
W83697HF/F
At the start of a command the FIFO is always disabled and command parameters must be sent based
upon the RQM and DIO bit settings in the main status register. When the FDC enters the command
execution phase, it clears the FIFO of any data to ensure that invalid data are not transferred.
An overrun and underrun will terminate the current command and the data transfer. Disk writes will
complete the current sector by generating a 00 pattern and valid CRC. Reads require the host to remove
the remaining data so that the result phase may be entered.
DMA transfers are enabled with the SPECIFY command and are initiated by the FDC by activating the
DRQ pin during a data transfer command. The FIFO is enabled directly by asserting DACK# and
addresses need not be valid.
Note that if the DMA controller is programmed to function in verify mode a pseudo read is performed by
the FDC based only on DACK#. This mode is only available when the FDC has been configured into byte
mode (FIFO disabled) and is programmed to do a read. With the FIFO enabled the above operation is
performed by using the new VERIFY command. No DMA operation is needed.¡@
3.1.3
Data Separator
The function of the data separator is to lock onto the incoming serial read data. When a lock is achieved
the serial front end logic of the chip is provided with a clock which is synchronized to the read data. The
sync hronized clock, called the Data Window, is used to internally sample the serial data portion of the
bit cell, and the alternate state samples the clock portion. Serial to parallel conversion logic separates
the read data into clock and data bytes.
The Digital Data Separator (DDS) has three parts: control logic, error adjustment, and speed tracking.
The DDS circuit cycles once every 12 clock cycles ideally. Any data pulse input will be synchronized
and then adjusted by immediate error adjustment. The control logic will generate RDD and RWD for
every pulse input. During any cycle where no data pulse is present, the DDS cycles are based on speed.
A digital integrator is used to keep track of the speed changes in the input data stream.
3.1.4
Write Precompensation
The write precompensation logic is used to minimize bit shifts in the RDDATA stream from the disk
drive. Shifting of bits is a known phenomenon in magnetic media and is dependent on the disk media
and the floppy drive.
The FDC monitors the bit stream t hat is being sent to the drive. The data patterns that require
precompensation are well known. Depending upon the pattern, the bit is shifted either early or late
relative to the surrounding bits.

3.1.5
Perpendicular Recording Mode
The FDC is also capable of interfacing directly to perpendicular recording floppy drives. Perpendicular
recording differs from the traditional longitudinal method in that the magnetic bits are oriented vertically.
This scheme packs more data bits into the same area.
FDCs with perpendicular recording drives can read standard 3.5" floppy disks and can read and write
perpendicular media. Some manufacturers offer drives that can read and write standard and
perpendicular media in a perpendicular media drive.
A single command puts the FDC into perpendicular mode. All other commands operate as they normally
do. The perpendicular mode requires a 1 Mbps data rate for the FDC. At this data rate the FIFO eases
the host interface bottleneck due to the speed of data transfer to or from the disk.
3.1.6
FDC Core
The W83697HF FDC is capable of performing twenty commands. Each command is initiated by a multibyte transfer from the microprocessor. The result can also be a multi-byte transfer back to the
microprocessor. Each command consists of three phases: command, execution, and result.
Command
The microprocessor issues all required information to the controller to perform a specific operation.
Execution
The controller performs the specified operation.
Result
After the operation is completed, status information and other housekeeping information is provided to
the microprocessor.

FIFO Register (R/W base address + 5)
The Data Register consists of four status registers in a stack with only one register presented to the
data bus at a time. This register stores data, commands, and parameters and provides diskette-drive
status information. Data bytes are passed through the data register to program or obtain results after a
command. In the W83697HF, this register defaults to FIFO disabled mode after reset. The FIFO can
change its value and enable its operation through the CONFIGURE command.

UART PORT
4.1
Universal Asynchronous Receiver/Transmitter (UART A, UART B)
The UARTs are used to convert parallel data into serial format on the transmit side and convert serial
data to pa rallel format on the receiver side. The serial format, in order of transmission and reception, is
a start bit, followed by five to eight data bits, a parity bit (if programmed) and one, one and half (five-bit
format only) or two stop bits. The UARTs are capable of handling divisors of 1 to 65535 and producing a
16x clock for driving the internal transmitter logic. Provisions are also included to use this 16x clock to
drive the receiver logic. The UARTs also support the MIDI data rate. Furthermore, the UARTs also
include complete modem control capability and a processor interrupt system that may be software
trailed to the computing time required to handle the communication link. The UARTs have a FIFO mode
to reduce the number of interrupts presented to the CPU. In each UART, there are 16-byte FIFOs for
both receive and transmit mode.
4.2
Register Address
4.2.1 UART Control Register (UCR) (Read/Write)
The UART Control Register controls and defines the protocol for asynchronous data communications,
including data length, stop bit, parity, and baud rate selection.

Set silence enable (SSE)
Baudrate divisor latch access bit (BDLAB)
Bit 7: BDLAB. When this bit is set to a logical 1, designers can access the divisor (in 16-bit binary
format) from the divisor latches of the baudrate generator during a read or write operation. When
this bit is reset, the Receiver Buffer Register, the Transmitter Buffer Register, or the Interrupt
Control Register can be accessed.
Bit 6: SSE. A logical 1 forces the Serial Output (SOUT) to a silent state (a logical 0). Only IRTX is
affected by this bit; the transmitter is not affected.
Bit 5: PBFE. When PBE and PBFE of UCR are both set to a logical 1,
(1) if EPE is logical 1, the parity bit is fixed as logical 0 to transmit and check.
(2) if EPE is logical 0, the parity bit is fixed as logical 1 to transmit and check.

Bit 4: EPE. This bit describes the number of logic 1's in the data word bits and parity bit only when bit 3
is programmed. When this bit is set, an even number of logic 1's are sent or checked. When the
bit is reset, an odd number of logic 1's are sent or checked.
Bit 3: PBE. When this bit is set, the position between the last data bit and the stop bit of the SOUT will
be stuffed with the parity bit at the transmitter. For the receiver, the parity bit in the same position
as the transmitter will be detected.
Bit 2: MSBE. This bit defines the number of stop bits in each serial character that is transmitted or
received.
(1) If MSBE is set to a logical 0, one stop bit is sent and checked.
(2) If MSBE is set to a logical 1, and data length is 5 bits, one and a half stop bits are sent and
checked.
(3) If MSBE is set to a logical 1, and data length is 6, 7, or 8 bits, two stop bits are sent and
checked.
Bits 0 and 1: DLS0, DLS1. These two bits define the number of data bits that are sent or checked in
each serial character.

Bit 7: RFEI. In 16450 mode, this bit is always set to a logic 0. In 16550 mode, this bit is set to a logic 1
when there is at least one parity bit error, no stop bit error or silent byte detected in the FIFO. In
16550 mode, this bit is cleared by reading from the USR if there are no remaining errors left in the
FIFO.
Bit 6: TSRE. In 16450 mode, when TBR and TSR are both empty, this bit will be set to a logical 1. In
16550 mode, if the transmit FIFO and TSR are both empty, it will be set to a logical 1. Other
thanthese two cases, this bit will be reset to a logical 0.
Bit 5: TBRE. In 16450 mode, when a data character is transferred from TBR to TSR, this bit will be set to
a logical 1. If ETREI of ICR is a logical 1, an interrupt will be generated to notify the CPU to write
the next data. In 16550 mode, this bit will be set to a logical 1 when the transmit FIFO is empty. It
will be reset to a logical 0 when the CPU writes data into TBR or FIFO.
Bit 4: SBD. This bit is set to a logical 1 to indicate that received data are kept in silent state for a full
word time, including start bit, data bits, parity bit, and stop bits. In 16550 mode, it indicates the
same condition for the data on top of the FIFO. When the CPU reads USR, it will clear this bit to a
logical 0.
Bit 3: NSER. This bit is set to a logical 1 to indicate that the received data have no stop bit. In 16550
mode, it indicates the same condition for the data on top of the FIFO. When the CPU reads
USR, it will clear this bit to a logical 0.
Bit 2: PBER. This bit is set to a logical 1 to indicate that the parity bit of received data is wrong. In 16550
mode, it indicates the same condition for the data on top of the FIFO. When the CPU reads USR,
it will clear this bit to a logical 0.
Bit 1: OER. This bit is set to a logical 1 to indicate received data have been overwritten by the next
received data before they were read by the CPU. In 16550 mode, it indicates the same condition
instead of FIFO full. When the CPU reads USR, it will clear this bit to a logical 0.
Bit 0: RDR. This bit is set to a logical 1 to indicate received data are ready to be read by the CPU in the
RBR or FIFO. After no data are left in the RBR or FIFO, the bit will be reset to a lo gical 0.

Bit 4: When this bit is set to a logical 1, the UA RT enters diagnostic mode by an internal loopback, as
follows:
(1) SOUT is forced to logical 1, and SIN is isolated from the communication link instead of the
TSR.
(2) Modem output pins are set to their inactive state.
(3) Modem input pins are isolated from the communication link and connect internally as DTR
(bit 0 of HCR) → DSR, RTS ( bit 1 of HCR) → CTS , Loopback RI input ( bit 2 of HCR) →
RI and IRQ enable ( bit 3 of HCR) → DCD .
Aside from the above connections, the UART operates normally. This method allows the CPU
to test the UART in a convenient way.
Bit 3: The UART interrupt output is enabled by setting this bit to a logic 1. In the diagnostic mode this bit
is internally connected to the modem control input DCD .
Bit 2: This bit is used only in the diagnostic mode. In the diagnostic mode this bit is internally
connected to the modem control input RI .
Bit 1: This bit controls the RTS output. The value of this bit is inverted and output to RTS .
Bit 0: This bit controls the DTR output. The value of this bit is inverted and output to DTR .

Programmable Baud Generator (BLL/BHL) (Read/Write)
Two 8-bit registers, BLL and BHL, compose a programmable baud generator
that uses 24 MHz to
16
generate a 1.8461 MHz frequency and divides it by a divisor from 1 to 2 -1. The output frequency of
the baud generator is the baud rate multiplied by 16, and this is the base frequency for the transmitter
and receiver. The table in the next page illustrates the use of the baud generator with a frequency of
1.8461 MHz. In high-speed UART mode (refer to CR0C bit7 and CR0C bit6), the programmable baud
generator directly uses 24 MHz and the same divisor as the normal speed divisor. In high-speed mode,
the data transmission rate can be as high as 1.5M bps.

Bit 7: This signal is active during data entry, when the printer is off-line during printing, when the print
head is changing position, or during an error state. When this signal is active, the printer is busy
and cannot accept data.
Bit 6: This bit represents the current state of the printer's ACK# signal. A 0 means the printer has
received a character and is ready to accept another. Normally, this signal will be active for
approximately 5 microseconds before BUSY# stops.
Bit 5: Logical 1 means the printer has detected the end of paper.
Bit 4: Logical 1 means the printer is selected.
Bit 3: Logical 0 means the printer has encountered an error condition.
Bit 1, 2: These two bits are not implemented and are logic one during a read of the status register.
Bit 0: This bit is valid in EPP mode only. It indicates that a 10 µS time-out has occurred on the EPP
bus. A logic 0 means that no time-out error has occurred; a logic 1 means that a time-out error
has been detected. Writing a logic 1 to this bit will clear the time-out status bit; writing a logic 0
has no effect.

and fixed at zero.
Bit 4: A 1 in this position allows an interrupt to occur when ACK# changes from low to high.
Bit 3: A 1 in this bit position selects the printer.
Bit 2: A 0 starts the printer (50 microsecond pulse, minimum).
Bit 1: A 1 causes the printer to line-feed after a line is printed.
Bit 0: A 0.5 microsecond minimum high active pulse clocks data into the printer. Valid data must be

Denotes an address or data read or write operation.
PD<0:7>
I/O
Bi-directional EPP address and data bus.
Intr
I
Used by peripheral device to interrupt the host.
nWait
I
Inactive to acknowledge that data transfer is completed. Act ive to indicate
that the device is ready for the next transfer.
PE
I
Paper end; same as SPP mode.
Select
I
Printer selected status; same as SPP mode.
nDStrb
O
This signal is active low. It denotes a data read or write operation.
nError
I
Error; same as SPP mode.
nInits
O
This signal is active low. When it is active, the EPP device is reset to its
initial operating mode.
nAStrb
O
This signal is active low. It denotes an address read or write operation.
6.2.8 EPP Operation
When the EPP mode is selected in the configuration register, the standard and bi-directional modes are
also available. The PDx bus is in the standard or bi-directional mode when no EPP read, write, or
address cycle is currently being executed. In this condition all output signals are set by the SPP Control
Port and the direction is controlled by DIR of the Control Port.
A watchdog timer is required to prevent system lockup. The timer indicates that more than 10 µS have
elapsed from the start of the EPP cycle to the time WAIT# is deasserted. The current EPP cycle is
aborted when a time-out occurs. The time-out condition is indicated in Status bit 0.
6.2.8.1 EPP Operation
The EPP operates on a two-phase cycle. First, the host selects the register within the device for
subsequent operations. Second, the host performs a series of read and/or write byte operations to the
selected register. Four operations are supported on the EPP: Address Write, Data Write, Address Read,
and Data Read. All operations on the EPP device are performed asynchronously.
6.2.8.2 EPP Version 1.9 Operation
The EPP read/write operation can be completed under the following conditions:
a. If the nWait is active low, when the read cycle (nWrite inactive high, nDStrb/nAStrb active low) or write
cycle (nWrite active low, nDStrb/nAStrb active low) starts, the read/write cycle proceeds normally and
will be completed when nWait goes inactive high.
b. If nWait is inactive high, the read/write cycle will not start. It must wait until nWait changes to active
low, at which time it will start as described above.
6.2.8.3 EPP Version 1.7 Operation
The EPP read/write cycle can start without checking whether nWait is active or inactive. Once the
read/write cycle starts, however, it will not terminate until nWait changes from active low to inactive high.

6.3 Extended Capabilities Parallel (ECP) Port
This port is software and hardware compatible with existing parallel ports, so it may be used as a
standard printer mode if ECP is not required. It provides an automatic high burst-bandwidth channel that
supports DMA for ECP in both the forward (host to peripheral) and reverse (peripheral to host) directions.
Small FIFOs are used in both forward and reverse directions to improve the maximum bandwidth
requirement. The size of the FIFO is 16 bytes. The ECP port supports an automatic handshake for the
standard parallel port to improve compatibility mode transfer speed.
The ECP port supports run -length-encoded (RLE) decompression (required) in hardware. Compression is
accomplished by counting identical bytes and transmitting an RL E byte that indicates how many times
the next byte is to be repeated. Hardware support for compression is optional.
For more information about the ECP Protocol, refer to the Extended Capabilities Port Protocol and ISA
Interface Standard.

6.3.5 cFifo (Parallel Port Data FIFO) Mode = 010
This mode is defined only for the forward direction. The standard parallel port protocol is used by a
hardware handshake to the peripheral to transmit bytes written or DMAed from the system to this FIFO.
Transfers to the FIFO are byte aligned.
6.3.6 ecpDFifo (ECP Data FIFO) Mode = 011
When the direction bit is 0, bytes written or DMAed from the system to this FIFO are transmitted by a
hardware handshake to the peripheral using the ECP parallel port protocol. Transfers to the FIFO are
byte aligned.
When the direction bit is 1, data bytes from the peripheral are read under automatic hardware handshake
from ECP into this FIFO. Reads or DMAs from the FIFO will return bytes of ECP data to the system.
6.3.7
tFifo (Test FIFO Mode) Mode = 110
Data bytes may be read, written, or DMAed to or from the system to this FIFO in any direction. Data in
the tFIFO will not be transmitted to the parallel port lines. However, data in the tFIFO may be displayed

to tri-state the data lines and reading the data register returns the value on the data
lines and not the value in the data register.
Parallel Port FIFO mode. This is the same as 000 except that bytes are written or
DMAed to the FIFO. FIFO data are automatically transmitted using the standard
parallel port protocol. This mode is useful only when direction is 0.
ECP Parallel Port Mode. When the direction is 0 (forward direction), bytes placed into
the ecpDFifo and bytes written to the ecpAFifo are placed in a single FIFO and auto
transmitted to the peripheral using ECP Protocol. When the direction is 1 (reverse
direction), bytes are moved from the ECP parallel port and packed into bytes in the
ecpDFifo.
Selects EPP Mode. In this mode, EPP is activated if the EPP mode is selected.

6.3.12 ECP Pin Descriptions
NAME
TYPE
DESCRIPTION
nStrobe (HostClk)
O
The nStrobe registers data or address into the slave on the
asserting edge during write operations. This signal handshakes
with Busy.
PD<7:0>
I/O
These signals contains address or data or RLE data.
nAck (PeriphClk)
I
This signal indicates valid data driven by the peripheral when
asserted. This signal handshakes with nAutoFd in reverse.
Busy (PeriphAck)
I
This signal deasserts to indicate that the peripheral can accept
data. It indicates whether the data lines contain ECP command
information or data in the reverse direction. When in reverse
direction, normal data are transferred when Busy (PeriphAck) is
high and an 8-bit command is transferred when it is low.
PError (nAckReverse)
I
This signal is used to acknowledge a change in the direction of
the transfer (asserted = forward). The peripheral drives this signal
low to acknowledge nReverseRequest. The host relies upon
nAckReverse to determine when it is permitted to drive the data
bus.
Select (Xflag)
I
Indicates printer on line.
nAut oFd (HostAck)
O
Requests a byte of data from the peripheral when it is asserted.
This signal indicates whether the data lines contain ECP address
or data in the forward direction. When in forward direction, normal
data are transferred when nAutoFd (HostAck) is high and an 8-bit
command is transferred when it is low.
nFault (nPeriphRequest)
I
Generates an error interrupt when it is asserted. This signal is
valid only in the forward direction. The peripheral is permitted (but
not required) to drive this pin low to request a reverse transfer
during ECP Mode.
nInit (nReverseRequest)
O
This signal sets the transfer direction (asserted = reverse,
deasserted = forward). This pin is driven low to place the channel
in the reverse direction.
nSelectIn (ECPMode)
O
This signal is always deasserted in ECP mode.

6.3.13 ECP Operation
The host must negotiate on the parallel port to determine if the peripheral supports the ECP protocol
before ECP operation. After negotiation, it is necessary to initialize some of the port bits. The following
are required:
(a) Set direction = 0, enabling the drivers.
(b) Set strobe = 0, causing the nStrobe signal to default to the deasserted state.
(c) Set autoFd = 0, causing the nAutoFd signal to default to the deasserted s tate.
(d) Set mode = 011 (ECP Mode)
ECP address/RLE bytes or data bytes may be sent automatically by writing the ecpAFifo or ecpDFifo,
respectively.
6.3.13.1 Mode Switching
Software will execute P1284 negotiation and all operation prior to a data transfer phase under
programmed I/O control (mode 000 or 001). Hardware provides an automatic control line handshake,
moving data between the FIFO and the ECP port only in the data transfer phase (mode 011 or 010).
If the port is in mode 000 or 001 it may switch to any other mode. If the port is not in mode 000 or 001 it
can only be switched into mode 000 or 001. The direction can be changed only in mode 001.
When in extended forward mode, the software should wait for the FIFO to be empty before switching
back to mode 000 or 001. In ECP reverse mode the software waits for all the data to be read from the
FIFO before changing back to mode 000 or 001.
6.3.13.2 Command/Data
ECP mode allows the transfer of normal 8-bit data or 8-bit commands. In the forward direction, normal
data are transferred when HostAck is high and an 8-bit command is transferred when HostAck is low.
The most significant bits of the command indicate whether it is a run-length count (for compression) or a
channel address.
In the reverse direction, normal data are transferred when PeriphAck is high and an 8-bit command is
transferred when PeriphAck is low. The most significant bit of the command is always zero.
6.3.13.3 Data Compression
The W83627HF supports run length encoded (RLE) decompression in hardware and can transfer
compressed data to a peripheral. Note that the odd (RLE) compression in hardware is not supported. In
order to transfer data in ECP mode, the compression count is written to the ecpAFifo and the data byte
is written to the ecpDFifo.
6.3.14
FIFO Operation
The FIFO threshold is set in configuration register 5. All data transfers to or from the parallel port can
proceed in DMA or Programmed I/O (non-DMA) mode, as indicated by the selected mode. The FIFO is
used by selecting the Parallel Port FIFO mode or ECP Parallel Port Mode. After a reset, the FIFO is
disabled.

W83697HF/F
6.3.15 DMA Transfers
DMA transfers are always to or from the ecpDFifo, tFifo, or CFifo. The DMA uses the standard PC DMA
services. The ECP requests DMA transfers from the host by activating the PDRQ pin. The DMA will
empty or fill the FIFO using the appropriate direction and mode. When the terminal count in the DMA
controller is reached, an interrupt is generated and serviceIntr is asserted, which will disable the DMA.
6.3.16
Programmed I/O (NON-DMA) Mode
The ECP or parallel port FIFOs can also be operated using interrupt driven programmed I/O.
Programmed I/O transfers are to the ecpDFifo at 400H and ecpAFifo at 000H or from the ecpDFifo
located at 400H, or to/from the tFifo at 400H. The host must set the direction, state, dmaEn = 0 and
serviceIntr = 0 in the programmed I/O transfers.
The ECP requests programmed I/O transfers from the host by activating the IRQ pin. The programmed
I/O will empty or fill the FIFO using the appropriate direction and mode.
6.4 Extension FDD Mode (EXTFDD)
In this mode, the W83627HF changes the printer interface pins to FDC input/output pins, allowing the
user to install a second floppy disk drive (FDD B) through the DB-25 printer connector. The pin
assignments for the FDC input/output pins are shown in Table 6-1.
After the printer interface is set to EXTFDD mode, the following occur:
(1) Pins MOB# and DSB# will be forced to inactive state.
(2) Pins DSKCHG# , RDATA#, WP# , TRAK0#, INDEX# will be logically ORed with pins PD4-PD0 to
serve as input signals to the FDC.
(3) Pins PD4-PD0 each will have an internal resistor of about 1K ohm to serve as pull-up resistor for FDD
open drain/collector output.
(4) If the parallel port is set to EXTFDD mode after the system has booted DOS or another operating
system, a warm reset is needed to enable the system to recognize the extension floppy drive.
6.5 Extension 2FDD Mode (EXT2FDD)
In this mode, the W83627HF changes the printer interface pins to FDC input/output pins, allowing the
user to install two extern al floppy disk drives through the DB-25 printer connector to replace internal
floppy disk drives A and B. The pin assignments for the FDC input/output pins are shown in Table6-1.
After the printer interface is set to EXTFDD mode, the following occur:
(1) P ins MOA#, DSA#, MOB#, and DSB# will be forced to inactive state.
(2) Pins DSKCHG# , RDATA#, WP#, TRAK0#, and INDEX# will be logically ORed with pins PD4-PD0 to
serve as input signals to the FDC.
(3) Pins PD4-PD0 each will have an internal resistor of about 1K ohm to serve as pull-up resistor for FDD
open drain/collector output.
(4) If the parallel port is set to EXT2FDD mode after the system has booted DOS or another operating
system, a warm reset is needed to enable the system to recognize the extension floppy drive.

7. GENERAL PURPOSE I/O
W83697HF provides 24 input/output ports that can be individually configured to perform a simple basic
I/O function or a pre-defined alternate function. Those 24 GP I/O ports are divided into three groups,
each group contains 8 port s. The first group is configured through control registers in logical device 7,
the second group in logical device 8, and the third group in logical device 9. Users can configure each
individual port to be an input or output port by programming respective bit in selection register (CRF0: 0 =
output, 1 = input). Invert port value by setting inversion register (CRF2: 0 = non -inverse, 1 = inverse).
Port value is read/written through data register (CRF1). Table 7.1 and 7.2 gives more details on GPIO's
assi gnment. In addition, GPIO1 is designed to be functional even in power loss condition (VCC or VSB
is off). Figure 7.1 shows the GP I/O port's structure. Right after Power-on reset, those ports default to
perform basic input function except ports in GPIO1 which maintains its previous settings until a battery
loss condition.

8. ACPI REGISTERS FEATURES
W83697HF supports both ACPI and legacy power managements. The switch logic of the power
management block generates an SMI interrupt in the legacy mode and an PME interrupt in the ACPI
mode. The new ACPI feature routes SMI / PME logic output either to SMI or to PME .The
SMI / PME logic routes to SMI only when both PME_EN = 0 and SMIPME_OE = 1. Similarly, the
SMI /PME logic routes to PME only when both PME_EN = 1 and SMIPME_OE = 1.

9. HARDWARE MONITOR
9.1
General Description
The W83697HF can be used to monitor several critical hardware parameters of the system, including
power supply voltages, fan speeds, and temperatures, which are very important for a high-end computer
system to work stable and properly. W83697HF provides LPC interface to access hardware .
An 8-bit analog-to-digital converter (ADC) was built inside W83697HF.
The W83697HF can
simultaneously monitor 7 analog voltage inputs, 2 fan tachometer inputs, 2 remote temperature, one
case-open detection signal. The remote temperature sensing can be performed by thermistors, or
TM
2N3904 NPN-type transistors, or directly from Intel Deschutes CPU thermal diode output. Also the
W83697HF provides: 2 PWM (pulse width modulation) outputs for the fan speed control; beep tone
output for warning; SMI#(through serial IRQ) , OVT#, GPO# signals for system protection events.
Through the application software or BIOS, the users can read all the monitored parameters of system
from time to time. And a pop-up warning can be also activated when the monitored item was out of the
TM
TM
proper/preset range. The application software could be Winbond's Hardware Doctor , or Intel LDCM
(LanDesk Client Management), or other management application software. Also the users can set up
the upper and lower limits (alarm thresholds) of these monitored parameters and to activate one
programmable and maskable interrupts. An optional beep tone could be used as warning signal when
the monitored parameters is out of the preset range.
9.2
Access Interface
The W83697HF provides two interface for microprocessor to read/write hardware monitor internal
registers.
9.2.1
LPC interface
The first interface uses LPC Bus to access which the ports of low byte (bit2~bit0) are defined in the port
5h and 6h. The other higher bits of these ports is set by W83697HF itself. The general decoded
address is set to port 295h and port 296h. These two ports are described as following:
Port 295h: Index port.
Port 296h: Data port.
The register structure is showed as the Figure 9.1

9.3 Analog Inputs
The maximum input voltage of the analog pin is 4.096V because the 8-bit ADC has a 16mv LSB. Really,
the application of the PC monitoring would most often be connected to power suppliers. The CPU V-core
voltage ,+3.3V ,battery and 5VSB voltage can directly connected to these analog inputs. The +12V,-12V
and -5V voltage inputs should be reduced a factor with external resistors so as to obtain the input range.

The value of R1 and R2 can be selected to 28K Ohms and 10K Ohms, respectively, when the input
voltage V1 is 12V. The node voltage of +12VIN can be subject to less t han 4.096V for the maximun input
range of the 8-bit ADC. The Pin 97 is connected to the power supply VCC with +5V. There are two
functions in this pin with 5V. The first function is to supply internal analog power in the W83697HF and
the second function is that this voltage with 5V is connected to internal serial resistors to monitor the
+5V voltage. The value of two serial resistors are 34K ohms and 50K ohms so that input voltage to ADC
is 2.98V which is less than 4.096V of ADC maximum input voltage. The express equation can represent
as follows.

The Pin 61 is connected to 5VSB voltage. W83697HF monitors this voltage and the internal two serial
resistors are 17K Ω and 33K Ω so that input voltage to ADC is 3.3V which less than 4.096V of ADC
maximum input voltage.
9.3.2
Monitor negative voltage:
The negative voltage should be connected two series resistors and a positive voltage VREF (is equal to
3.6V). In the Figure 9.2, the voltage V2 and V3 are two negative voltage which they are -12V and -5V
respectively. The voltage V2 is connected to two serial resistors then is connected to another terminal
VREF which is positive voltage. So as that the voltage node N12VIN can be obtain a posedge voltage if
the scales of the two serial resirtors are carefully selected. It is recommanded from Winbond that the
scale of two serial resistors are R3=232K ohms and R4=56K ohm. The input voltage of node N12VIN can
be calculated by following equation.
N 12VIN = (VREF + V2 ) × (
232 KΩ
) + V2
232 KΩ + 56 KΩ
where VREF is equal 3.6V.
If the V2 is equal to -12V then the voltage is equal to 0.567V and the converted hexdecimal data is set
to 35h by the 8-bit ADC with 16mV-LSB.This monitored value should be converted to the real negative
votage and the express equation is shown as follows.
V2 =
N 12VIN − VREF × β
1− β
Where β is 232K/(232K+56K). If the N2VIN is 0.567 then the V2 is approximately equal to -12V.
The another negative voltage input V3 (approximate -5V) also can be evaluated by the similar method
and the serial resistors can be selected with R5=120K ohms and R6=56K ohms by the Winbond
recommended. The expression equation of V3 With -5V voltage is shown as follows.
V3 =
N 5VIN − VREF × γ
1 −γ
Where the γ is set to 120K/(120K+56K). If the monitored ADC value in the N5VIN channel is 0.8635,
VREF=3.6V and the parameter γ is 0.6818 then the negative voltage of V3 can be evalated to be -5V.

transistor 2N3904 and the circuit connection is shown as Figure 9.3. The pin of Pentium II D- is
connected to power supply ground (GND) and the pin D+ is connected to pin VTINx in the W83697HF.
The resistor R=30K ohms should be connected to VREF to supply the diode bias current and the
bypass capacitor C=3300pF should be added to filter the high frequency noise. The transistor 2N3904
should be connected to a form with a diode, that is, the Base (B) and Collector (C) in the 2N3904 should
be tied togeter to act as a thermal diode.

FAN Speed Count and FAN Speed Control
9.4.1
Fan speed count
Inputs are provides for signals from fans equipped with tachometer outputs. The level of these signals
should be set to TTL level, and maximum input voltage can not be over +5.5V. If the input signals from
the tachometer outputs are over the VCC, the external trimming circuit should be added to reduce the
voltage to obtain the input specification. The normal circuit and trimming circuits are shown as Figure
9.4.
Determine the fan counter according to:
Count =
1.35 × 10 6
RPM × Divisor
In other words, the fan speed counter has been read from register CR28 or CR29 or CR2A, the fan speed
can be evaluated by the following equation.
RPM
=
×10 6
× Divisor
1 .3 5
Count
The default divisor is 2 and defined at CR47.bit7~4, and Bank0 CR5D.bit5~7 which are three bits for
divisor. That provides very low speed fan counter such as power supply fan. The followed table is an
example for the relation of divisor, PRM, and count.

Fan speed control
The W83697HF provides 2 sets for fan PWM speed control. The duty cycle of PWM can be programmed
by a 8-bit registers which are defined in the Bank0 CR5A and CR5B. The default duty cycle is set to
100%, that is, the default 8-bit registers is set to FFh. The expression of duty can be represented as
follows.

SMI# interrupt mode
9.5.1
Voltage SMI# mode :
SMI# interrupt for voltage is Two-Times Interrupt Mode. Voltage exceeding high limit or going below
low limit will causes an interrupt if the previous interrupt has been reset by reading all the interrupt
Status Register. (Figure 9.6 )
9.5.2
Fan SMI# mode :
SMI# interrupt for fan is Two-Times Interrupt Mode. Fan count exceeding the limit, or exceeding and
then going below the limit, will causes an interrupt if the previous interrupt has been reset by reading

The W83697HF temperature sensor 1 SMI# interrupt has two modes:
(1) Comparator Interrupt Mode
Setting the THYST (Temperature Hysteresis) limit to 127 °C will set temperature sensor 1 SMI# to the
Comparator Interrupt Mode. Temperature exceeds TO (Over Temperature) Limit causes an interrupt
and this interrupt will be reset by reading all the Interrupt Status Register. Once an interrupt event
has occurred by exceeding TO, then reset, if the temperature remains above the TO , the interrupt
will occur again when the next conversion has completed. If an interrupt event has occurred by
exceeding TO and not reset, the interrupts will not occur again. The interrupts will continue to
occur in this manner until the temperature goes below TO. (Figure 9.8 )
(2) Two-Times Interrupt Mode
Setting the THYST lower than TO will set temperature sensor 1 SMI# to the Two-Times Interrupt Mode.
Temperature exceeding TO causes an interrupt and then temperature going below THYST will also
cause an interrupt if the previous interrupt has been reset by reading all the interrupt Status
Register. Once an interrupt event has occurred by exceeding TO, then reset, if the temperature
remains above the THYST , the interrupt will not occur. (Figure 9.9 )
(3) One-Time Interrupt Mode
Temperature exceeding TO causes an interrupt and then temperature going below THYST will not cause
an interrupt. Once an interrupt event has occurred by exceeding TO , then going below THYST an
interrupt will not occur again until the temperature exceeding TO . (Figure 9.9)

9.5.4 The W83697HF temperature sensor 2 SMI# interrupt has two modes and it is programmed
at CR[4Ch] bit 6.
(1) Comparator Interrupt Mode:
Temperature exceeding TO causes an interrupt and this interrupt will be reset by reading all the
Interrupt Status Register. Once an interrupt event has occurred by exceeding TO, then reset, if the
temperature remains above the THYST, the interrupt will occur again when the next conversion has
completed. If an interrupt event has occurred by exceeding TO and not reset, the interrupts will not
occur again. The interrupts will continue to occur in this manner until the temperature goes below
THYST. ( Figure 9.10 )
(2) Two-Times Interrupt Mode(Default):
Temperature exceeding TO causes an interrupt and then temperature going below THYST will also
cause an interrupt if the previous interrupt has been reset by reading all the interrupt Status
Register. Once an interrupt event has occurred by exceeding TO , then reset, if the temperature
remains above the THYST , the interrupt will not occur. (Figure 9.11 )

9.6 OVT# interrupt mode
The OVT# signal is only related with temperature sensor 2.
9.6.1 The W83697HF temperature sensor 2 Over-Temperature (OVT#) has the following
modes
(1) Comparator Mode(Default):
Setting Bank1/2 CR[52h] bit 2 to 0 will set OVT# signal to comparator mode. Temperature
exceeding TO causes the OVT# output activated until the temperature is less than THYST. ( Figure
9.12)
(2) Interrupt Mode:
Setting Bank1/2 CR[52h] bit 2 to 1 will set OVT# signal to interrupt mode. Setting Temperature
exceeding TO causes the OVT# output activated indefinitely until reset by reading temperature
sensor 2 or sensor 3 registers. Temperature exceeding TO , then OVT# reset, and then temperature
going below THYST will also cause the OVT# activated indefinitely until reset by reading temperature
sensor2 or sensor 3 registers. Once the OVT# is activated by exceeding TO , then reset, if the
temperature remains above THYST , the OVT# will not be activated again.( Figure 9.12)
Temperature sensor 2 and 3 Over-Temperature output (OVT#) in ACPI mode
Setting CR[4Ch] bit 1 to 1 will set OVT# signal to ACPI mode. At this mode, temperature exceeding
one level of temperature separation, starting from 0 degree, causes the OVT# output activated.
OVT# will be activated again once temperature exceeding the next level. OVT# output will act the
same manner when temperature goes down. (Figure 17,18). If temperature goes around the
current level, the OVT# will not act.(Refer the arrow in the figure). The granularity of temperature
separation between each OVT# output signal can be programmed at Bank0 CR[5Fh].
The priority of this mode is higher than Comparator mode and Interrupt mode .

10 CONFIGURATION REGISTER
10.1 Plug and Play Configuration
The W83697HF uses Compatible PNP protocol to access configuration registers for setting up different
types of configurations. In W83697HF, there are eleven Logical Devices (from Logical Device 0 to
Logical Device B with the exception of logical device 4 for backward compatibility) which correspond to
eleven individual functions: FDC (logical device 0), PRT (logical device 1), UART1 (logical device 2),
UART2 (logical device 3), CIR (Consumer IR, logical device 6), GPIO1 (logical device 7), GPIO5(logical
device 8),GPIO2 ~GPIO4(logical device 9), ACPI ((logical device A), and Hardware monitor (logical
device B). Each Logical Device has its own configuration registers (above CR30). Host can access
those regi sters by writing an appropriate logical device number into logical device select register at CR7.
10.2 Compatible PnP
10.2.1 Extended Function Registers
In Compatible PnP, there are two ways to enter Extended Function and read or write the configuration
registers. HEFRAS (CR26 bit 6) can be used to select one out of these two methods of entering the
Extended Function mode as follows:
HEFRAS
address and value
0
write 87h to the location 2Eh twice
1
write 87h to the location 4Eh twice
- 132 -
Publication Release Date: Feb. 2002
Revision 0.70
W83697HF/F
After Power-on reset, the value on RTSA# (pin 49) is latched by HEFRAS of CR26. In Compatible PnP,
a specific value (87h) must be written twice to the Extended Functions Enable Register (I/O port address
2Eh or 4Eh). Secondly, an index value (02h, 07h -FFh) must be written to the Extended Functions Index
Register (I/O port address 2Eh or 4Eh same as Extended Functions Enable Register) to identify which
configuration register is to be accessed. The designer can then access the desired configuration
register through the Extended Functions Data Register (I/O port address 2Fh or 4Fh).
After programming of the configuration register is finished, an additional value (AAh) should be written to
EFERs to exit the Extended Function mode to prevent unintentional access to those configuration
registers. The designer can also set bit 5 of CR26 (LOCKREG) to high to protect the configuration
registers against accidental accesses.
The configuration registers can be reset to their default or hardware settings only by a cold reset (pin MR
= 1). A warm reset will not affect the configuration registers.
10.2.2 Extended Functions Enable Registers (EFERs)
After a power-on reset, the W83697HF enters the default operating mode. Before the W83697HF enters
the extended function mode, a specific value must be programmed into the Extended Function Enable
Register (EFER) so that the extended function register can be accessed. The Extended Function
Enable Registers are write-only registers. On a PC/AT system, their port addresses are 2Eh or 4Eh (as
described in previous section).
10.2.3 Extended Function Index Registers (EFIRs), Extended Function Data Registers(EFDRs)
After the extended function mode is entered, the Extended Function Index Register (EFIR) must be
loaded with an index value (02h, 07h-FEh) to access Configuration Register 0 (CR0), Configuration
Register 7 (CR07) to Configuration Register FE (CRFE), and so forth through the Extended Function
Data Register (EFDR). The EFIRs are write-only registers with port address 2Eh or 4Eh (as described in
section 12.2.1) on PC/AT systems; the EFDRs are read/write registers with port address 2Fh or 4Fh (as
described in section 9.2.1) on PC/AT systems.

10.3 Configuration Sequence
To program W83697HF configuration registers, the following configuration sequence must be followed:
(1). Enter the extended function mode
(2). Configure the configuration registers
(3). Exit the extended function mode
10.3.1 Enter the extended function mode
To place the chip into the extended function mode, two successive wrtites of 0x87 must be applied to
Extended Function Enable Registers(EFERs, i.e. 2Eh or 4Eh).
10.3.2 Configurate the configuration registers
The chip selects the logical device and activates the desired logical devices through Extended Function
Index Register(EFIR) and Extended Function Data Register(EFDR). EFIR is located at the same address
as EFER, and EFDR is located at address (EFIR+1).
First, write the Logical Device Number (i.e.,0x07) to the EFIR and then write the number of the desired
logical device to the EFDR. If accessing the Chip(Global) Control Registers, this step is not required.
Secondly, write the address of the desired configuration register within the logical device to the EFIR and
then write (or read) the desired configuration register through EFDR.
10.3.3 Exit the extended function mode
To exit the extended function mode, one write of 0xAA to EFER is required. Once the chip exits the
extended function mode, it is in the normal running mode and is ready to enter the configuration mode.
10.3.4 Software programming example
The following example is written in Intel 8086 assembly language. It assumes that the EFER is located
at 2Eh, so EFIR is located at 2Eh and EFDR is located at 2Fh. If HEFRAS (CR26 bit 6) is set, 4Eh can
be directly replaced by 4Eh and 2Fh replaced by 4Fh.
