9.9.1
Port 8 is a 5-bit input/output port that is also used for CS
to IRQ
In modes 1 to 6 (expanded modes), port 8 can provide CS
to IRQ
In mode 7 (single-chip mode), port 8 can provide IRQ
selection of pin functions in single-chip mode.
The IRQ
input or output. For details see section 5, Interrupt Controller.
Pins in port 8 can drive one TTL load and a 90-pF capacitive load. They can also drive a
darlington transistor pair.
