Section 7 I/O Ports
7.3
7.3.1
Port 2 is an 8-bit input/output port which also has an address output function. It’s pin
configuration is shown in figure 7.2. The pin functions differ according to the operating mode.
In modes 1 to 4 (expanded modes with on-chip ROM disabled), port 2 consists of address bus
output pins (A
port 2 data direction register (P2DDR) can designate pins for address bus output (A
generic input. In modes 6 and 7 (single-chip mode), port 2 is a generic input/output port.
Port 2 has software-programmable built-in pull-up transistors.
Pins in port 2 can drive one TTL load and a 90-pF capacitive load. They can also drive an LED or
a darlington transistor pair.
