7.6.1
Port 5 is a 3-bit input/output port that is multiplexed with input/output pins (TxD
serial communication interface 0. The port 5 pin functions are the same in all operating modes.
Figure 7.13 shows the pin configuration of port 5.
Pins in port 5 can drive one TTL load and a 30-pF capacitive load. They can also drive a
darlington transistor.
