7. I/O Ports
7.2
7.2.1
Port 4 is an 8-bit input/output port which also functions as a data bus. It's pin configuration is
shown in figure 7.1. The pin functions differ depending on the operating mode.
In the H8/3008, 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.
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.
