7.12.1
Port B is an 8-bit input/output port that is multiplexed with the host interface data bus. The pin
functions differ depending on the operating mode. Figure 7.19 shows the pin configuration of port
B.
Port B has program-controllable built-in MOS input pull-up transistors.
Pins in port B can drive one TTL load and a 90-pF capacitive load. They can also drive a
darlington transistor.
