Section 9 I/O Ports
9.5
9.5.1
Port 4 is an 8-bit input/output port with the pin configuration shown in figure 9.4. The pin
functions differ according to the operating mode.
In modes 1 to 6 (expanded modes), when the bus width control register (ABWCR) designates
areas 0 to 7 all as 8-bit-access areas, the chip operates in 8-bit bus mode and port 4 is a generic
input/output port. When at least one of areas 0 to 7 is designated as a 16-bit-access area, the chip
operates in 16-bit bus mode and port 4 becomes part of the data bus. In mode 7 (single-chip
mode), port 4 is a generic input/output port.
Port 4 has software-programmable built-in pull-up MOS.
Pins in port 4 can drive one TTL load and a 90-pF capacitive load. They can also drive a
darlington transistor pair.
