8.4.1
Port 3 is an 8-bit input/output port also used for data bus, with the pin configuration shown in
figure 8.3. Port 3 is a data bus in modes 1 to 5 (expanded modes) and a generic input/output port
in mode 7 (single-chip mode).
Pins in port 3 can drive one TTL load and a 90-pF capacitive load. They can also drive a
darlington transistor pair.
