Intel’s 80960Hx Processor
Intel’s 80960Hx processor provides new performance levels while maintaining backward
compatibility (pin1 and software) with the i960 CA/CF processor. This newest member of the family
of i960 32-bit, RISC-style, embedded processors allows customers to create scalable designs that
meet multiple price and performance points. This is accomplished by providing processors that can
run at the bus speed or faster using Intel’s clock multiplying technology (Table 1).The 80960Hx core
is capable of issuing 150 million instructions per second, using a sophisticated instruction scheduler
that allows the processor to sustain a throughput of two instructions every core clock, with a peak
performance of three instructions per clock. The 80960Hx-series comprises three processors, which
differ in the ratio of core clock speed to external bus speed.

80960HA/HD/HT
In addition to expanded clock frequency options, the 80960Hx provides essential enhancements for
an emerging class of high-performance embedded applications. Features include a larger
instruction cache, data cache, and data RAM than any other 80960 processor to date. It also boasts
a 32-bit demultiplexed and pipelined burst bus, fast interrupt mechanism, guarded memory unit,
wait state generator, dual programmable timers, ONCE and IEEE 1149.1-compliant boundary scan
test and debug support, and new instructions.
2.1
The i960® Processor Family
The i960 processor family is a 32-bit RISC architecture created by Intel to serve the needs of
embedded applications. The embedded market includes applications as diverse as industrial
automation, avionics, image processing, graphics and communications.
Because all members of the i960 processor family share a common core architecture, i960
applications are code-compatible. Each new processor in the family adds its own special set of
functions to the core to satisfy the needs of a specific application or range of applications in the
embedded market.
2.2
Key 80960Hx Features
2.2.1
Execution Architecture
Independent instruction paths inside the processor allow the execution of multiple, out-of-sequence
instructions per clock. Register and resource scoreboarding interlocks maintain the logical integrity
of sequential instructions that are being executed in parallel. To sustain execution of multiple
instructions in each clock cycle, the processor decodes multiple instructions in parallel and
simultaneously issues these instructions to parallel processing units. The various processing units
are then able to independently access instruction operands in parallel from a common register set.
Local Register Cache integrated on-chip provides automatic register management on call/return
instructions. Upon a call instruction, the processor allocates a set of local registers for the called
procedure, then stores the registers for the previous procedure in the on-chip register cache. As
additional procedures are called, the cache stores the associated registers such that the most recently
called procedure is the first available by the next return (ret) instruction. The processor can store up to
fifteen register sets, after which the oldest sets are stored (spilled) into external memory.
The 80960Hx supports the 80960 architecturally-defined branch prediction mechanism. This
allows many branches to execute with no pipeline break. With the 80960Hx’s efficient pipeline, a
branch can take as few as zero clocks to execute. The maximum penalty for an incorrect prediction
is two core clocks.
2.2.2
Pipelined, Burst Bus
A 32-bit high performance bus controller interfaces the 80960Hx core to the external memory and
peripherals. The Bus Control Unit features a maximum transfer rate of 160 Mbytes per second (at a
40 MHz external bus clock frequency). A key advantage of this design is its versatility. The user
can independently program the physical and logical attributes of system memory. Physical
attributes include wait state profile, bus width, and parity. Logical attributes include cacheability
and Big or Little Endian byte order. Internally programmable wait states and 16 separately
configurable physical memory regions allow the processor to interface with a variety of memory
2
Advance Information Datasheet
80960HA/HD/HT
subsystems with minimum system complexity. To reduce the effect of wait states, the bus design is
decoupled from the core. This lets the processor execute instructions while the bus performs
memory accesses independently.
The Bus Controller’s key features include:
•
•
•
•
•
•
•
•
2.2.3
Demultiplexed, Burst Bus to support most efficient DRAM access modes
Address Pipelining to reduce memory cost while maintaining performance
32-, 16- and 8-bit modes to facilitate I/O interfacing
Full internal wait state generation to reduce system cost
Little and Big Endian support
Unaligned Access support implemented in hardware
Three-deep request queue to decouple the bus from the core
Independent physical and logical address space characteristics
On-Chip Caches and Data RAM
As shown in Figure 1, the 80960Hx provides generous on-chip cache and storage features to
decouple CPU execution from the external bus. The processor includes a 16 Kbyte instruction
cache, an 8 Kbyte data cache and 2 Kbytes of Data RAM. The caches are organized as 4-way set
associative. Stores that hit the data cache are written through to memory. The data cache performs
write allocation on cache misses. A fifteen-set stack frame cache allows the processor to rapidly
allocate and deallocate local registers. All of the on-chip RAM sustains a 4-word (128-bit) access
every clock cycle.
2.2.4
Priority Interrupt Controller
The interrupt unit provides the mechanism for the low latency and high throughput interrupt
service essential for embedded applications. A priority interrupt controller provides full
programmability of 240 interrupt sources with a typical interrupt task switch (latency) time of 17
core clocks. The controller supports 31 priority levels. Interrupts are prioritized and signaled within
10 core clocks of the request. If the interrupt has a higher priority than the processor priority, the
context switch to the interrupt routine would typically complete in another 7 bus clocks.
External agents post interrupts via the 8-bit external interrupt port. The Interrupt unit also handles
the two internal sources from the Timers. Interrupts can be level- or edge-triggered.
2.2.5
Guarded Memory Unit
The Guarded Memory Unit (GMU) provides memory protection without the address translation
found in Memory Management Units. The GMU contains two memory protection schemes: one
prevents illegal memory accesses, the other detects memory access violations. Both signal a fault
to the processor. The programmable protection modes are: user read, write or execute; and
supervisor read, write or execute.

80960HA/HD/HT
2.2.6
Dual Programmable Timers
The processor provides two independent 32-bit timers, with four programmable clock rates. The
user configures the timers via the Timer Unit registers. These registers are memory-mapped within
the 80960Hx, addressable on 32-bit boundaries. The timers have a single-shot mode and
auto-reload capabilities for continuous operation. Each timer has an independent interrupt request
to the processor’s interrupt controller.
2.2.7
Processor Self Test
When a system error is detected, the FAIL pin is asserted, a fail code message is driven onto the
address bus, and the processor stops execution at the point of failure. The only way to resume
normal operation is to perform a RESET operation. Because System Error generation can occur
sometime after the bus confidence test and even after initialization during normal processor
operation, the FAIL pin is HIGH (logic “1”) before the detection of a System Error.
The processor uses only one read bus-transaction to signal the fail code message; the address of the
bus transaction is the fail code itself. The fail code is of the form: 0xfeffffnn; bits 6 to 0 contain a
mask recording the possible failures. Bit 7, when set to 1, indicates that the mask contains failures
from the internal Built-In Self-Test (BIST); when 0, the mask indicates other failures.
Ignore reserved bits 0 and 1. Also ignore bits 5 and 6 when bit 7 is clear (=0).
The mask is shown in Table 2 and Table 3.

ADDRESS BUS carries the upper 30 bits of the physical address. A31 is the most
significant address bit and A2 is the least significant. During a bus access, A31:2
identify all external addresses to word (4-byte) boundaries. The byte enable
signals indicate the selected byte in each word. During burst accesses, A3 and A2
increment to indicate successive addresses.
I/O
D31:0
S(L)
H(Z)

DATA BUS carries 32, 16, or 8-bit data quantities depending on bus width
configuration. The least significant bit of the data is carried on D0 and the most
significant on D31. The lower 8 data lines (D7:0) are used when the bus is
configured for 8-bit data. When configured for 16-bit data, D15:0 are used.
DATA PARITY carries parity information for the data bus. Each parity bit is
assigned a group of 8 data bus pins as follows:
I/O
DP3:0
S(L)
H(Z)
B(Z)
R(Z)
DP3 generates/checks parity for D31:24
DP2 generates/checks parity for D23:16
DP1 generates/checks parity for D15:8
DP0 generates/checks parity for D7:0
Parity information is generated for a processor write cycle and is checked for a
processor read cycle. Parity checking and polarity are programmable. Parity
generation/checking is only performed for the size of the data accessed.
O
PCHK
H(Q)
B(Q)
R(1)
PARITY CHECK indicates the result of a parity check operation. An asserted
PCHK indicates that the previous bus read access resulted in a parity check error.
BYTE ENABLES select which of the four bytes addressed by A31:2 are active
during a bus access. Byte enable encoding is dependent on the bus width of the
memory region accessed:

BE2 enables D23:16
BE1 enables D15:8
BE0 enables D7:0
16-bit bus:
BE3 becomes Byte High Enable (enables D15:8)
BE2 is not used (state is undefined)
BE1 becomes Address Bit 1 (A1)
BE0 becomes Byte Low Enable (enables D7:0)
8-bit bus:
BE3 is not used (state is undefined)
BE2 is not used (state is undefined)
BE1 Address Bit 1 (A1)
BE0 Address Bit 0 (A0)
WRITE/READ is low for read accesses and high for write accesses. W/R
becomes valid during the address phase of a bus cycle and remains valid until the
end of the cycle for non-pipelined accesses. For pipelined accesses, W/R
changes state when the next address is presented.
0= Read
1= Write
DATA/CODE indicates that a bus access is a data access or an instruction
access. D/C has the same timing as W/R.
0 = Code
1 = Data

Description
SUPERVISOR ACCESS indicates whether the current bus access originates from
a request issued while in supervisor mode or user mode. SUP can be used by the
memory subsystem to isolate supervisor code and data structures from
non-supervisor access.

ADDRESS STROBE indicates a valid address and the start of a new bus access.
ADS is asserted for the first clock of a bus access.
READY, when enabled for a memory region, is asserted by the memory
subsystem to indicate the completion of a data transfer. READY is used to
indicate that read data on the bus is valid, or that a write transfer has completed.
READY works in conjunction with the internal wait state generator to
accommodate various memory speeds. READY is sampled after any programmed
wait states:
During each data cycle of a burst access
During the data cycle of a non-burst access

BURST TERMINATE, when enabled for a memory region, is asserted by the
memory subsystem to terminate a burst access in progress. When BTERM is
asserted, the current burst access is terminated and another address cycle
occurs.
WAIT indicates the status of the internal wait-state generator. WAIT is asserted
when the internal wait state generator generates NWAD, NRAD, NWDD and NRDD
wait states. WAIT can be used to derive a write data strobe.
BURST LAST indicates the last transfer in a bus access. BLAST is asserted in the
last data transfer of burst and non-burst accesses after the internal wait-state
generator reaches zero. BLAST remains active as long as wait states are inserted
via the READY pin. BLAST becomes inactive after the final data transfer in a bus
cycle.
DATA TRANSMIT/RECEIVE indicates direction for data transceivers. DT/R is
used with DEN to provide control for data transceivers connected to the data bus.
DT/R is driven low to indicate the processor expects data (a read cycle). DT/R is
driven high when the processor is “transmitting” data (a store cycle). DT/R only
changes state when DEN is high.
0 = Data Receive
1 = Data Transmit
DATA ENABLE indicates data transfer cycles during a bus access. DEN is
asserted at the start of the first data cycle in a bus access and de-asserted at the
end of the last data cycle. DEN remains asserted for an entire bus request, even
when that request spans several bus accesses. For example, a ldq instruction
starting at an unaligned quad word boundary is one bus request spanning at least
two bus accesses. DEN remains asserted throughout all the accesses (including
ADS states) and de-asserts when the Iqd instruction request is satisfied. DEN is
used with DT/R to provide control for data transceivers connected to the data bus.
DEN remains asserted for sequential reads from pipelined memory regions.
BUS LOCK indicates that an atomic read-modify-write operation is in progress.
LOCK may be used by the memory subsystem to prevent external agents from
accessing memory that is currently involved in an atomic operation (e.g., a
semaphore). LOCK is asserted in the first clock of an atomic operation and
de-asserted when BLAST is deasserted in the last bus cycle.

HOLD REQUEST signals that an external agent requests access to the
processor’s address, data, and control buses. When HOLD is asserted, the
processor:
HOLD
I
S(L)
Completes the current bus request.
Asserts HOLDA and floats the address, data, and control buses.
When HOLD is deasserted, the HOLDA pin is deasserted and the processor
reassumes control of the address, data, and control pins.
O
HOLDA
H(1)
B(0)
R(Q)
HOLD ACKNOWLEDGE indicates to an external master that the processor has
relinquished control of the bus. The processor grants HOLD requests and enters
the HOLDA state while the RESET pin is asserted.
HOLDA is never granted while LOCK is asserted.
BUS BACKOFF forces the processor to immediately relinquish control of the bus
on the next clock cycle. When READY/BTERM is enabled and:
BOFF
I
S(L)
When BOFF is asserted, the address, data, and control buses are floated on the
next clock cycle and the current access is aborted.
When BOFF is deasserted, the processor resumes by regenerating the aborted
bus access.
See Figure 16 on page 40 for BOFF timing requirements.

BUS REQUEST indicates that a bus request is pending in the bus controller.
BREQ does not indicate whether or not the processor is stalled. See BSTALL for
processor stall status. BREQ can be used with BSTALL to indicate to an external
bus arbiter the processor’s bus ownership requirements.
BUS STALL indicates that the processor has stalled pending the result of a
request in the bus controller. When BSTALL is asserted, the processor must
regain bus ownership to continue processing (i.e., it can no longer execute strictly
out of on-chip cache memory).
CYCLE TYPE indicates the type of bus cycle currently being started or processor
state. CT3:0 encoding follows:

EXTERNAL INTERRUPT pins are used to request interrupt service. These pins
can be configured in three modes:
I
XINT7:0
A(E)
A(L)
Dedicated Mode: Each pin is assigned a dedicated interrupt level. Dedicated
inputs can be programmed to be level (low or high) or edge (rising or falling)
sensitive.
Expanded Mode: All eight pins act as a vectored interrupt source. The interrupt
pins are level sensitive in this mode.
Mixed Mode: The XINT7:5 pins act as dedicated sources and the XINT4:0 pins act
as the five most significant bits of a vectored source. The least significant bits of
the vectored source are set to “010” internally.
NMI

I
A(E)
NON-MASKABLE INTERRUPT causes a non-maskable interrupt event to occur.
NMI is the highest priority interrupt source. NMI is falling edge triggered.

Description
CLOCK INPUT provides the time base for the 80960Hx. All internal circuitry is
synchronized to CLKIN. All input and output timings are specified relative to
CLKIN.
For the 80960HD, the 2x internal clock is derived by multiplying the CLKIN
frequency by 2. For the 80960HT, the 3x internal clock is derived by multiplying
the CLKIN frequency by 3.
RESET forces the device into reset. RESET causes all external and internal
signals to return to their reset state (if defined). The rising edge of RESET starts
the processor boot sequence.
SELF TEST, when asserted during the rising edge of RESET, causes the
processor to execute its built in self-test.
FAIL indicates a failure of the processor’s built-in self-test performed during
initialization. FAIL is asserted immediately out of reset and toggles during self-test
to indicate the status of individual tests. If self-test passes, FAIL is de-asserted
and the processor branches to the user’s initialization code. When self-test fails,
the FAIL pin asserts and the processor ceases execution.
ONCE
I
ON-CIRCUIT EMULATION control: the processor samples this pin during reset. If
it is asserted low at the end of reset, the processor enters ONCE mode. In ONCE
mode, the processor stops all clocks and floats all output pins except the TDO pin.
ONCE uses an internal pull-up resistor; see RPU definition in Table 21 “80960Hx
DC Characteristics” on page 32. Pull this pin high when not in use.
TCK
I
TEST CLOCK provides the clocking function for IEEE 1149.1 Boundary Scan
testing.
TDI
I
TEST DATA INPUT is the serial input pin for IEEE 1149.1 Boundary Scan testing.
TDI uses an internal pull-up resistor; see RPU definition in Table 21 “80960Hx DC
Characteristics” on page 32.
TDO
O
TEST DATA OUTPUT is the serial output pin for IEEE 1149.1 Boundary Scan
testing. ONCE does not disable this pin.
TRST
I
TEST RESET asynchronously resets the Test Access Port (TAP) controller. TRST
must be held low at least 10,000 clock cycles after power-up. One method is to
provide TRST with a separate power-on-reset circuit. TRST includes an internal
pull-up resistor; see RPU definition in Table 21 “80960Hx DC Characteristics” on
page 32. Pull this pin low when not in use.
TMS
I
TEST MODE SELECT is sampled at the rising edge of TCK. TCK controls the
sequence of TAP controller state changes for IEEE 1149.1 Boundary Scan
testing. TMS uses an internal pull-up resistor; see RPU definition in Table 21
“80960Hx DC Characteristics” on page 32.
VCC5
I
5 V REFERENCE VOLTAGE input is the reference voltage for the 5 V-tolerant I/O
buffers. Connect this signal to +5 V for use with inputs which exceed 3.3 V. When
all inputs are from 3.3 V components, connect this signal to 3.3 V.
VCCPLL
I
PLL VOLTAGE is the +3.3 VDC analog input for the PLL.
O
VOLTAGE DETECT signal allows external system logic to distinguish between a
5 V 80960Cx processor and the 3.3 V 80960Hx processor. This signal is active
low for a 3.3 V 80960Hx (it is high impedance for 5 V 80960Cx). This pin is
available only on the PGA version.

80960HA/HD/HT
3.3
Package Thermal Specifications
The 80960Hx is specified for operation when TC (case temperature) is within the range of
0°C–85°C. TC may be measured in any environment to determine whether the 80960Hx is within
the specified operating range. Measure the case temperature at the center of the top surface,
opposite the pins. Refer to Figure 5.
TA (ambient temperature) is calculated from θCA (thermal resistance from case to ambient) using
the equation:
TA = TC – P*θCA
Table 12 shows the maximum TA allowable (without exceeding TC) at various airflows and
operating frequencies (fCLKIN).
Note that TA is greatly improved by attaching fins or a heatsink to the package. P (maximum power
consumption) is calculated by using the typical ICC as tabulated in Section 4.6, “DC
Specifications” on page 32 and VCC of 3.3 V.

Heat Sink Adhesives
Intel recommends silicone-based adhesives to attach heat sinks to the PGA package. There is no
particular recommendation concerning the PQ4 package.
3.5
PowerQuad4 Plastic Package
The 80960Hx family is available in an improved version of the common 208-lead SQFP plastic
package called the PowerQuad4* (PQ4). The PQ4 package dimensions and lead pitch are identical
to the SQFP package and the former PQ2 package, so the PQ4 fits into the same board footprint.
The advantage of the PQ4 package is the superior thermal conductivity that allows the plastic
version of the 80960Hx to operate with the same 0-85°C temperature specifications as the more
expensive ceramic PGA package.
The PQ4 package integrates a copper heat sink within the package to dissipate heat effectively. See
Table 14 and Table 15.

Stepping Register Information
The memory-mapped register at FF008710H contains the 80960Hx Device ID. The ID is identical
to the ID obtained from a JTAG Query. Figure 6 defines the current 80960Hx Device IDs. The
value for device identification is compliant with the IEEE 1149.1 specification and Intel standards.
Table 16 describes the fields of the device ID.

Recommended Connections
Power and ground connections must be made to multiple VCC and VSS (GND) pins. Every
80960Hx-based circuit board should include power (VCC) and ground (VSS) planes for power
distribution. Every VCC pin must be connected to the power plane; every VSS pin must be connected to
the ground plane. Pins identified as “NC” —no connect pins—must not be connected in the system.
Liberal decoupling capacitance should be placed near the 80960Hx. The processor can cause transient
power surges when its output buffers transition, particularly when connected to large capacitive loads.
Low inductance capacitors and interconnects are recommended for best high-frequency electrical
performance. Inductance can be reduced by shortening the board traces between the processor and
decoupling capacitors as much as possible. Capacitors specifically designed for PGA packages
offer the lowest possible inductance.
For reliable operation, always connect unused inputs to an appropriate signal level. In particular,
any unused interrupt (XINT7:0, NMI) input should be connected to VCC through a pull-up resistor,
as should BTERM if not used. Pull-up resistors should be in the range of 20 KΩ for each pin tied
high. If READY or HOLD are not used, the unused input should be connected to ground. N.C. pins
must always remain unconnected.
4.4
VCC5 Pin Requirements (VDIFF)
In mixed-voltage systems that drive 80960Hx processor inputs in excess of 3.3 V, the VCC5 pin must
be connected to the system’s 5 V supply. To limit current flow into the VCC5 pin, there is a limit to
the voltage differential between the VCC5 pin and the other VCC pins. The voltage differential
between the 80960Hx VCC5 pin and its 3.3 V VCC pins should never exceed 2.25 V. This limit
applies to power-up, power-down, and steady-state operation. Table 20 outlines this requirement.
Meeting this requirement ensures proper operation and guarantees that the current draw into the
VCC5 pin does not exceed the ICC5 specification.
If the voltage difference requirements cannot be met due to system design limitations, an alternate
solution may be employed. As shown in Figure 7, a minimum of 100 Ω series resistor may be used
to limit the current into the VCC5 pin. This resistor ensures that current drawn by the VCC5 pin
does not exceed the maximum rating for this pin.
Figure 7. VCC5 Current-Limiting Resistor
VCC5 Pin
+5 V (±0.25 V)
100 Ω
(±5%, 0.5 W)
This resistor is not necessary in systems that can guarantee the VDIFF specification.
In 3.3 V-only systems and systems that drive 80960Hx pins from 3.3 V logic, connect the VCC5
pin directly to the 3.3 V VCC plane.

4.5
VCCPLL Pin Requirements
If the voltage on the VCCPLL power supply pin exceeds the VCC pin voltage by 0.5 V at any time,
including the power up and power down sequences, excessive currents can permanently damage
on-chip electrostatic discharge (ESD) protection diodes. The damage can accumulate over
multiple episodes.
Pragmatically, this problem only occurs when the VCCPLL and VCC pins are driven by separate
power supplies or voltage regulators. Applications that use one power supply for VCCPLL and
VCC are not typically at risk. Verify that your application does not allow the VCCPLL voltage to
exceed VCC by 0.5 V.
The VCCPL low-pass filter recommended in the Developer’s Manual does not promote this
problem.

1. See Section 4.8, “AC Timing Waveforms” on page 38 for waveforms and definitions.
2. See Figure 25 “Output Delay or Hold vs. Load Capacitance” on page 44 for capacitive derating information
for output delays and hold times.
3. See Figure 22 “Rise and Fall Time Derating at 85°C and Minimum VCC” on page 43 for capacitive derating
information for rise and fall times.
4. Where N is the number of NRAD, NRDD, NWAD or NWDD wait states that are programmed in the Bus
Controller Region Table. WAIT never goes active when there are no wait states in an access.
5. N = Number of wait states inserted with READY.
6. These specifications are guaranteed by the processor.
7. These specifications must be met by the system for proper operation of the processor.
8. RESET is an asynchronous input that has no required setup and hold time for proper operation. However,
to guarantee the device exits the reset mode synchronized to a particular clock edge, the rising edge of
RESET must meet setup and hold times to the rising edge of the CLKIN.
9. The interrupt pins are synchronized internally by the 80960Hx. They have no required setup or hold times
for proper operation. These pins are sampled by the interrupt controller every clock and must be active for
at least two consecutive CLKIN rising edges when asserting them asynchronously. To guarantee
recognition at a particular clock edge, the setup and hold times shown must be met.
10.Relative Output timings are not tested.
11.Not tested.
12.The processor minimizes changes to the bus signals when transitioning from a bus cycle to an idle bus for
the following signals: A31:4, SUP, CT3:0, D/C, LOCK, W/R, BE3:0.

AC Test Conditions
AC values are derived using the 50 pF load shown in Figure 8. Figure 25 “Output Delay or Hold vs.
Load Capacitance” on page 44, shows how timings vary with load capacitance. Input waveforms
(except for CLKIN) are assumed to have a rise and fall time of ≤ 2 ns from 0.8 V to 2.0 V.

Note: READY adds memory access time to data transfers, whether or not the
bus access is a burst access. BTERM interrupts a bus access, whether or not
the bus access has more data transfers pending. Either the READY signal or
the BTERM signal terminates a bus access when the signal is asserted during
the last (or only) data transfer of the bus access.

Figure 49. BREQ and BSTALL Operation
CLKIN
ADS
BLAST
BREQ
BSTALL
The processor can stall (BSTALL asserted) even with an empty bus queue (BREQ deasserted).
Depending on the instruction stream and memory wait states, the two signals can be separated by
several CLKIN cycles.
Bus arbitration logic that logically “ANDs” BSTALL and BREQ will not correctly grant the bus to
the processor in all stall cases, potentially degrading processor performance.
Do not logically “AND” BSTALL and BREQ together in arbitration logic. Instead, the simplest
bus arbitration should logically “OR” BSTALL and BREQ to determine the processor’s bus
ownership requirements.
More sophisticated arbitration should recognize the priority nature of these two signals. Using a
traffic light analogy, BREQ is a “yellow light” warning of a possible processor stall and BSTALL
is a “red light” indicating a stall in progress.

NOTE:
1. When the PMCON for the region has External Ready Control enabled, wait states are inserted as
long as READY and BTERM are de-asserted. When Read Pipelining is enabled, the Ta state of the
subsequent read access is concurrent with the last data cycle of the access. Because External
Ready Control is disabled for Read Pipelining, the address cycle occurs during BLAST.

- - Boundary-Scan Description Language (BSDL Version 0.0) is a de-facto standard
means of describing essential features of ANSI/IEEE 1149.1-1990 compliant
devices. This language is under consideration by the IEEE for formal inclusion
within a supplement to the 1149.1-1990 standard. The generation of the supplement
entails an extensive IEEE review and a formal acceptance balloting procedure
which may change the resultant form of the language. Be aware that this process
may extend well into 1993, and at this time the IEEE does not endorse or hold an
opinion on the language.

-- Boundary-Scan Description Language (BSDL Version 0.0) is a de-facto

compliant devices.
This language is under consideration by the IEEE for formal
inclusion within a supplement to the 1149.1-1990 standard.
The generation of the
supplement entails an extensive IEEE review and a formal acceptance balloting
procedure which may change the resultant form of the language.
Be aware that this
process may extend well into 1993, and at this time the IEEE does not endorse or
hold an opinion on the language.
