9.2.1
Port 1 is an 8-bit input/output port with the pin configuration shown in figure 9.1. The pin
functions differ between the expanded modes with on-chip ROM disabled, expanded modes with
on-chip ROM enabled, and single-chip mode. In modes 1 to 4 (expanded modes with on-chip
ROM disabled), they are address bus output pins (A
In modes 5 and 6 (expanded modes with on-chip ROM enabled), settings in the port 1 data
direction register (P1DDR) can designate pins for address bus output (A
In mode 7 (single-chip mode), port 1 is a generic input/output port.
When DRAM is connected to area 3, A
cycles. For details see section 7, Refresh Controller.
Pins in port 1 can drive one TTL load and a 90-pF capacitive load. They can also drive a
darlington transistor pair.
