9.2 Port 4
9.2.1 Overview
Port 4 is an 8-bit input/output port with the pin configuration shown in figure 9-1. The pin
functions differ between the 8-bit and 16-bit bus modes.
When the bus width control register (ABWCR) designates areas 0 to 7 all as 8-bit-access areas,
the H8/3003 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 H8/3003 operates in 16-bit bus mode
and port 4 becomes the lower data bus.
Port 4 has software-programmable built-in pull-up transistors.
Pins in port 4 can drive one TTL load and a 90-pF capacitive load. They can also drive a
darlington transistor pair.
