Port 2 is an 8-bit input/output port with the pin configuration shown in figure 7.5. The pin
functions differ depending on the operating mode.
Port 2 has built-in, programmable MOS input pull-up transistors that can be used in modes 2 and
3.
Pins in port 2 can drive one TTL load and a 90-pF capacitive load. They can also drive LEDs and
darlington transistors.
