Section 7 I/O Ports
7.4
7.4.1
Port 3 is an 8-bit input/output port which also functions as a data bus. It’s pin configuration is
shown in figure 7.3. Port 3 is a data bus in modes 1 to 5 (expanded modes) and a generic
input/output port in modes 6 and 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.
7.4.2
Table 7.5 summarizes the registers of port 3.
