Port 3 is an 8-bit input/output port that is multiplexed with the data bus and host interface data bus.
Figure 7.9 shows the pin configuration of port 3. The pin functions differ depending on the
operating mode.
Port 3 has built-in, programmable MOS input pull-up transistors that can be used in mode 3.
Pins in port 3 can drive one TTL load and a 90-pF capacitive load. They can also drive a
darlington transistor.
