Section 9 I/O Ports
9.4
9.4.1
Port 3 is an 8-bit input/output port with the pin configuration shown in figure 9.3. Port 3 is a data
bus in modes 1 to 6 (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.
9.4.2
Table 9.5 summarizes the registers of port 3.
