IRQ
Interrupt Request (Open Drain Output).
This output
goes low when an interrupt occurs in any channel. IRQ
returns high when all the interrupts have been read from
the Interrupt FIFO Register. A pull-up resistor (1K typical)
is required at this output.
R11
10
DS
Data Strobe (Input)
. This active low input works in
conjunction with CS to enable the read and write
operations.
R13
11
CS
Chip Select (Input).
This active low input is used by a
microprocessor to activate the microprocessor port.
R5
12
R/W
Read/Write (Input)
. This input controls the direction of the
data bus lines (D7-D0) during a microprocessor access.
R7

DTA
Data Transfer Acknowledgment (Open Drain Output)
.
This active low output indicates that a data bus transfer is
completed. A pull-up resistor (1K typical) is required at this
output.
