7.1
The H8/3008 has six input/output ports (ports 4, 6, 8, 9, A, and B) and one input-only port (port
7). Table 7.1 summarizes the port functions. The pins in each port are multiplexed as shown in
table 7.1.
Each port has a data direction register (DDR) for selecting input or output, and a data register
(DR) for storing output data. In addition to these registers, port 4 has an input pull-up MOS
control register (PCR) for switching input pull-up MOS transistors on and off.
Ports 4, 6, and 8 can drive one TTL load and a 90-pF capacitive load. Ports 9, A, and B can drive
one TTL load and a 30-pF capacitive load. Ports 4, 6, 8, 9, A, and B can drive a darlington pair.
