10A.9 Port C
10A.9.1 Overview
Port C is an 8-bit I/O port. Port C pins also function as a 14-bit PWM output (PWM0 and PWM1)
and as an address bus outputs. The pin functions change according to the operating mode.
Port C has a built-in MOS input pull-up function that can be controlled by software.
Figure 10A.8 shows the port C pin configuration.
