RD: Read Operation
In parallel Intel microprocessor interface mode, this pin is asserted low by the microprocessor to initiate
a read cycle. Data is output to D[7:0] from the device.
DS: Data Strobe
In parallel Motorola microprocessor interface mode, this pin is the data strobe of the parallel interface.
During a write operation (RW=0), data on D[7:0] is sampled into the device. During a read operation
(RW=1), data is output to D[7:0] from the device.
WR: Write Operation
In parallel Intel microprocessor interface mode, this pin is asserted low by the microprocessor to initiate
a write cycle. Data on D[7:0] is sampled into the device during a write operation.
RW: Read/Write Select
In parallel Motorola microprocessor interface mode, this pin is asserted low for write operation and high
for read operation.
D[7:0]: Data Bus
These pins function as a bi-directional data bus of the microprocessor interface.
A[7:0]: Address Bus
These pins function as an address bus of the microprocessor interface.
CS: Chip Select
For each read or write operation, this pin must be changed from high to low, and remains low until the
operation is over.
INT: Interrupt Request
A low level on this pin indicates that an interrupt is pending inside the chip.
EMD[7:0]: Data Bus
Data Input/Output pins for the external SRAM. Used for data exchange between the IDT82V2608 and
the external SRAM.
