Type
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.
Microprocessor Address Bus: 15-bit address bus
used by the Host Processor for accessing the Envoy-
CE4 for a read/write cycle. UPA14 is the Most
Significant Bit (MSB).
