Overview
The H8/3052BF has 10 input/output ports (ports 1, 2, 3, 4, 5, 6, 8, 9, A, and B) and one input port
(port 7). Table 9.1 summarizes the port functions. The pins in each port are multiplexed as shown
in table 9.1.
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, ports 2, 4, and 5 have an input pull-up
MOS control register (PCR) for switching input pull-up MOS transistors on and off.
Ports 1 to 6 and port 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 1 to 6 and 8 to B can drive a darlington
pair. Ports 1, 2, 5, and B can drive LEDs (with 10-mA current sink). Pins P8
