Pin Functions for Each Mode

(1) Modes 4 and 5

In mode 4 and 5, port C pins function as address outputs automatically.

Figure 10-13 shows the port C pin functions.

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 10-14 shows the port C pin functions.
