7.2.1
Port 1 is an 8-bit input/output port also used for address output, with the pin configuration shown
in figure 7.1. The pin functions differ according to the operating mode. In modes 1 to 4 (expanded
modes with on-chip ROM disabled), they are address bus output pins (A
In mode 5 (expanded modes with on-chip ROM enabled), settings in the port 1 data direction
register (P1DDR) can designate pins for address bus output (A
and 7 (single-chip mode), port 1 is a generic input/output port.
Pins in port 1 can drive one TTL load and a 90-pF capacitive load. They can also drive an LED or
a darlington transistor pair.
