Microprocessor Clock: This clock should come
from the microprocessor being interfaced to this
device. For Intel and Motorola modes, it is
recommended that this lead be connected to the
microprocessor bus clock. In Motorola mode, this
clock must be synchronous to the microprocessor
bus clock. Maximum frequency of 66 MHz, minimum
frequency of 33 MHz.
Chip Select: Chip select lead from Host. Active low
assertion.
Transfer Acknowledge: Active low signal indicating
normal completion of the bus transfer. This output
requires an external pull-up resistor.
Note: Device asserts this high before tri-stating to
improve acknowledge timing.
Hardware Reset: An active low pulse with minimum
width of 1 ms which must be applied after power is
applied to reset all registers, counters, and FIFOs.
The reset is asynchronous going into the reset state,
but requires all external clocks to be active and
stable during the reset state.
Test Mode: For TranSwitch testing purposes only.
