9.3.1
Port 2 is an 8-bit input/output port with the pin configuration shown in figure 9.2. 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
in the port 2 data direction register (P2DDR) can designate pins for address bus output (A
or generic input. In mode 7 (single-chip mode), port 2 is a generic input/output port.
When DRAM is connected to area 3, A
cycles. For details see section 7, Refresh Controller.
Port 2 has software-programmable built-in pull-up MOS. Pins in port 2 can drive one TTL load
and a 90-pF capacitive load. They can also drive a darlington transistor pair.
