Port 9 is a 6-bit input/output port that is also used for input and output (TxD
SCK
and IRQ
The IRQ
for input or output. For details see section 5, Interrupt Controller.
Port 9 has the same set of pin functions in all operating modes. Figure 9.9 shows the pin
configuration of port 9.
Pins in port 9 can drive one TTL load and a 30-pF capacitive load. They can also drive a
darlington transistor pair.
