5.2 Port 1
Port 1 is an 8-bit input/output port that also provides the low bits of the address bus. The function
of port 1 depends on the MCU mode as indicated in table 5-2.

Mode 1
Address bus (low)
(A
* Depending on the bit settings in the data direction register: 0—input pin; 1—address pin
Pins of port 1 can drive a single TTL load and a 90-pF capacitive load when they are used as output
pins. They can also drive light-emitting diodes or a Darlington pair.
