9.3 Pin Functions For Each Mode - Renesas H8S/2633 Series Hardware Manual

10A.9.3 Pin Functions for Each Mode
(1) Modes 4 and 5
In modes 4 and 5, port C pins function as address outputs automatically.
Figure 10A-13 shows the port C pin functions.

(2) Mode 6
In mode 6, port C pints function as address outputs or input ports and I/O can be specified in bit
units. When each bit in PCDDR is set to 1, the corresponding pin functions as an address output
and when the bit cleared to 0, the pin functions as a PWM output and an input port.
Figure 10A-14 shows the port C pin functions.
