FDC The Floppy Disk Controller provides the interface between a host processor and one floppy disk drives. It integrates a controller and a digital data separator with write pre-compensation, data rate selection logic, microprocessor interface, and a set of registers. The FDC supports data transfer rates of 250 Kbps, 300 Kbps, 500 Kbps, and 1 Mbps. It operates in PC/AT mode and supports 3-mode type drives. The FDC configuration is handled by software and a set of Configuration registers. Status, Data, and Control registers facilitate the interface between the host microprocessor and the disk drive, providing information about the condition and/or state of the FDC. These configuration registers can select the data rate, enable interrupts, drives, and DMA modes, and indicate errors in the data or operation of the FDC/FDD. The controller manages data transfers using a set of data transfer and control commands. These commands are handled in three phases: Command, Execution, and Result. Not all commands utilize all these three phases. The below content is about the FDC device register descriptions. All the registers are for software porting reference. -14- May, 2008 V0.27P F71883 Status Register A (PS/2 mode) Base + 0 Bit Name R/W Default Description 7 INTPEND R 0 This bit indicates the state of the interrupt output. 6 DRV2_N R - 0: a second drive has been installed. 1: a second drive has not been installed. 5 STEP R 0 This bit indicates the complement of STEP# disk interface output. 4 TRK0_N R - This bit indicates the state of TRK0# disk interface input. 3 HDSEL R 0 This bit indicates the complement of HDSEL# disk interface output. 0: side 0. 1: side 1. 2 INDEX_N R - This bit indicates the state of INDEX# disk interface input. 1 WPT_N R - This bit indicates the state of WPT# disk interface input. 0: disk is write-protected. 1: disk is not write-protected. 0 DIR R 0 This bit indicates the complement of DIR# disk interface output.

ST0 = 80h UART The F71883 provides two UART ports and supports IRQ sharing for system application. The UARTs are used to convert data between parallel format and serial format. They convert parallel data into serial format on transmission and serial format into parallel data on receiver -28- May, 2008 V0.27P F71883 side. The serial format is formed by one start bit, followed by five to eight data bits, a parity bit if programmed and one ( 1.5 or 2 ) stop bits. The UARTs include complete modem control capability and an interrupt system that may be software trailed to the computing time required to handle the communication link. They have FIFO mode to reduce the number of interrupts presented to the host. Both receiver and transmitter have a 16-byte FIFO.

Therefore the voltage under 2.048V (ex:1.5V) can be directly connected to these analog inputs. The voltage higher than 2.048V should be reduced by a factor with external -35- May, 2008 V0.27P F71883 resistors so as to obtain the input range. Only 3Vcc is an exception for it is main power of the F71883. Therefore 3Vcc can directly connect to this chip’s power pin and need no external resistors. There are two functions in this pin with 3.3V. The first function is to supply internal analog power of the F71883 and the second function is that voltage with 3.3V is connected to internal serial resistors to monitor the +3.3V voltage. The internal serial resistors are two 150K ohm, so that the internal reduced voltage is half of +3.3V. There are four voltage inputs in the F71883 and the voltage divided formula is shown as follows: VIN = V+12V × R2 R1 + R2 where V+12V is the analog input voltage, for example. If we choose R1=27K, R2=5.1K, the exact input voltage for V+12v will be 1.907V, which is within the tolerance. As for application circuit, it can be refer to the figure shown as follows.

Remote-sensor transistor manufacturers Manufacturer Model Number Panasonic 2SB0709 2N3906 Philips PMBT3906 Monitor Temperature from “thermistor” The F71883 can connect three thermistor to measure environment temperature or remote temperature.

In the Figure 7-1, the thermistor is connected by a serial resistor with 10K ohm, then connected to VREF. Monitor Temperature from “thermal diode” Also, if the CPU, GPU or external circuits provide thermal diode for temperature measurement, the F71883 is capable to these situations. The build-in reference table is for PNP 2N3906 transistor, and each different kind of thermal diode should be matched with specific offset and BJT gain. In the Figure 7-1, the transistor is directly connected into temperature pins. ADC Noise Filtering The ADC is integrating type with inherently good noise rejection. Micro-power operation -37- May, 2008 V0.27P F71883 places constraints on high-frequency noise rejection; therefore, careful PCB board layout and suitable external filtering are required for high-accuracy remote measurement in electronically noisy environment. High frequency EMI is best filtered at D+ and D- with an external 2200pF capacitor. Too high capacitance may introduce errors due to the rise time of the switched current source. Nearly all noise sources tested cause the ADC measurement to be higher than the actual temperature, depending on the frequency and amplitude. Over Temperature Signal (OVT#) OVT# alert for temperature is shown as figure 7-3. When monitored temperature exceeds the over-temperature threshold value, OVT# will be asserted until the temperature goes below the hysteresis temperature. To T HYST OVT# Fig 7-3 Temperature PME# PME# interrupt for temperature is shown as figure 7-4.

Linear auto mode. More detail, please refer the description of registers. Manual mode For manual mode, it generally acts as software fan speed control. Stage auto mode At this mode, the F71883 provides automatic fan speed control related to temperature variation of CPU/GPU or the system. The F71883 can provide four temperature boundaries and five intervals, and each interval has its related fan speed count. All these values should be set by BIOS first. Take figure 7-11 as example. When temperature boundaries are set as 45, 55, 65, and 75°C and there are five intervals (each interval is 10(C). The related desired fan speed counts for each interval are 0500h, 0400h, 0300h, 0200h and 0100h. When the temperature is within 55~65(C, the fan speed count 300h will be load into FAN EXPECT COUNT that define in registers. Then, the F71883 will adjust PWMOUT duty-cycle to meet the expected value. It can be said that the fan will be turned on with a specific speed set by BIOS and automatically controlled with the temperature variation.

The temp.-fan speed monitoring and flash interval is 1sec. c. Once temp. goes over 70°C, fan speed will directly increase to full speed 6000RPM. If set the hysteresis as 5°C, once temp reduces under 65°C (not 70°C), fan speed reduces from full speed and decrease linearly with temp.. PWMOUT Duty-cycle operating process In both “Manual RPM” and “Temperature RPM” modes, the F71883 adjust PWMOUT duty-cycle according to current fan count and expected fan count. It will operate as follows: (1). When expected count is 0xFFF, PWMOUT duty-cycle will be set to 0x00 to turn off fan. (2). When expected count is 0x000, PWMOUT duty-cycle will be set to 0xFF to turn on fan with full speed. (3). If both (1) and (2) are not true, (4). When PWMOUT duty-cycle decrease to MIN_DUTY(≠ 00h), obviously the duty-cycle will decrease to 00h next, the F71883 will keep duty-cycle at 00h for 1.6 seconds. After that, the F71883 starts to compare current fan count and expected count in order to increase or decrease its duty-cycle. This ensures that if there is any glitch during the period, the F71883 will ignore it. Start Duty Stop Duty Fig 7-12 FAN_FAULT# Fan_Fault# will be asserted when the fan speed doesn’t meet the expected fan speed within a programmable period (default is 11 seconds) or when fan stops with respect to PWM duty-cycle which should be able to turn on the fan. There are two conditions may cause the FAN_FAULT# event. (1). When PWM_Duty reaches 0xFF, the fan speed count can’t reach the fan expected count in time.

After the period of detecting fan full speed, when PWM_Duty > Min. Duty, and fan count still in 0xFFF. 7.6 Keyboard Controller The KBC provides the functions included a keyboard and a PS/2 mouse, and can be used with IBM(-compatible personal computers or PS/2-based systems. The controller receives serial data from the keyboard or PS/2 mouse, checks the parity of the data, and presents the data to the system as a byte of data in its output buffer. The controller will assert an interrupt to the system when data are placed in its output buffer. The below content is about the KBC device register descriptions. All the registers are for software porting reference. Status Register The status register is an 8 bits register at I/O address 64h that provides information about the status of the KBC Bit Name R/W Default Description 7 Parity error R 0 0:odd parity 1:even parity 6 Time out R 0 0:no time out error 1:time out error 5 Auxiliary device OBF R 0 0: Auxiliary output buffer empty 1: Auxiliary output buffer full 4 Inhinit R 0 0:keyboard is inhibited 1: keyboard is not inhibited 3 Command/data R 0 0:data byte 1:command byte 2 SYSTEM_FLAG R 0 This bit is set or clear by command byte of KBC 1 IBF R 0 0:input buffer empty 1: input buffer full 0 OBF R 0 0:output buffer empty 1: output buffer full -45- May, 2008 V0.27P F71883 Command register The internal KBC operation is controlled by the KBC command byte (KCCB). The KCCB resides in I/O address 64h that is read with a 20h command and written with a 60h command data. Bit Name 7 Reserved 6 R/W Default Description - - Reserved Translate code R/W 1 0: Pass un-translated scan code. 1: Translate scan code to IBM PC standard. 5 Disable Auxiliary Device R/W 0 1: Disable Auxiliary inhibit function. 4 Disable Keyboard R/W 0 1: Disable keyboard inhibit function. 3 Reserved - - Reserved 2 System flag R/W 1 0: The system is executing POST as a result of a cold boot. 1: The system is executing POST as a result of a shutdown or warm boot. 1 Enable Auxiliary Interrupt R/W 1 0: Ao interrupt 1: A system interrupt is generated when a byte is placed in output buffer (IRQ12). 0 Enable keyboard Interrupt R/W 1 0:No interrupt 1: A system interrupt is generated when a byte is placed in output buffer (IRQ1). DATA register The DATA register is an 8 bits register at I/O address 60h. the KBC used the output buffer to send the scan code received from keyboard and data byte replay by command to the system. Power on default <7:0> = 00000000 binary 7.7 SPI Interface Communication between the two devices is handling the serial peripheral interface (SPI). Every SPI system consist of one master and one or more slaves, where a master provides the SPI clock and slave receives clock from the master. This design is only master function, for basic signal, master-out/slave-in (MOSI), master-in/slave-out (MISO), serial clock (SCK), and 4 slaves select (SS), are needed for SPI interface. Each of slave select supports from 512kbits to 4096kbits flash is decided by configuration register. Serial clock (SCK) signal frequency is varied from 24MHz to 187.5 KHz. The serial data (MOSI) for SPI interface translates to depend on SCK rising edge or falling edge is decided by configuration register. -46- May, 2008 V0.27P F71883 7.8 80 Port Monitor the value of 0x80 port and output the value via the signals defined for 7-segment display. High nibble and low nibble are outputted interleaved at 1KHz frequency. 7.9 ACPI Function The Advanced Configuration and Power Interface (ACPI) is a system for controlling the use of power in a computer. It lets computer manufacturer and user to determine the computer’s power usage dynamically. There are three ACPI states that are of primary concern to the system designer and they are designated S0, S3 and S5. S0 is a full-power state; the computer is being actively used in this state. The other two are called sleep states and reflect different power consumption when power-down. S3 is a state that the processor is powered down but the last procedural state is being stored in memory which is still active. S5 is a state that memory is off and the last procedural state of the processor has been stored to the hard disk. Take S3 and S5 as comparison, since memory is fast, the computer can quickly come back to full-power state, the disk is slower than the memory and the computer takes longer time to come back to full-power state. However, since the memory is off, S5 draws the minimal power comparing to S0 and S3. It is anticipated that only the following state transitions may happen: S0→S3, S0→S5, S5→S0, S3→S0 and S3→S5. Among them, S3→S5 is illegal transition and won’t be allowed by state machine. It is necessary to enter S0 first in order to get to S5 from S3. As for transition S5→S3 will occur only as an immediate state during state transition from S5→S0. It isn’t allowed in the normal state transition. The below diagram described the timing, the always on and always off, keep last state could be set in control register. In keep last state mode, one register will keep the status of before power loss. If it is power on before power loss, it will remain power on when power is resumed, otherwise, if it is power off before power loss, it will remain power off when power is resumed. -47- May, 2008 V0.27P F71883 VBAT VSB RSMRST# S3# PS_ON# PSIN# PSOUT# VCC3V DEFAULT TIMING Always off VBAT VSB RSMRST# S3# PS_ON# PSIN# PSOUT# VCC3V ALways ON TIMING PCI Reset and PWROK Signals The F71883 supports 3 output buffers for 3 reset signals.

PWROK is delayed 400ms (default) as VCC arrives 2.8V, and the delay timing can be programmed by register. (100ms ~ 400ms) In the figure, the RSTCON# will be implemented by register RSTCON_EN. If RSTCON_EN be set to 0, the RSTCON# pin will affect PWROK output(Default). If RSTCON_EN be set to 1, the RSTCON# pin will affect PCIRST outputs.

Register Description The configuration register is used to control the behavior of the corresponding devices. To configure the register, using the index port to select the index and then writing data port to alter the parameters. The default index port and data port are 0x4E and 0x4F respectively. Pull down the SOUT1 pin to change the default value to 0x2E/0x2F. To enable configuration, the entry key 0x87 must be written to the index port. To disable configuration, write exit key 0xAA to the index port. Following is a example to enable configuration and disable configuration by using debug. -o 4e 87 -o 4e 87 ( enable configuration ) -o 4e aa ( disable configuration ) The Following is a register map (total devices) grouped in hexadecimal address order, which shows a summary of all registers and their default value.
