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 (1 K typical) is required at this
output.
Data Strobe (Input). This active low input works
in conjunction with CS to enable the read and
write operations.
Chip Select (Input). This active low input is used
by a microprocessor to activate the
microprocessor port.
Read/Write (Input). This input controls the
direction of the data bus lines (D7-D0) during a
microprocessor access.
Data Transfer Acknowledgment (Open Drain
Output). This active low output indicates that a
data bus transfer is completed. A pull-up resistor
(1 K typical) is required at this output.
Data Bus D0 - D7 (Bidirectional). These pins
form the 8-bit bidirectional data bus of the
microprocessor port.
Address A0 to A10 (Input). These inputs provide
the A10 - A0 address lines to the internal
registers.
