10B.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 10B-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 an input port.
Figure 10B-14 shows the port C pin functions.
