7.5.1
Port 4 is an 8-bit input/output port that is multiplexed with input/output pins (TMRI
TMCI
0 and 1. In slave mode, P4
host interrupt requests are available for general input/output.
Figure 7.12 shows the pin configuration of port 4.
Pins in port 4 can drive one TTL load and a 90-pF capacitive load. They can also drive a
darlington transistor.
