Port C
10.9.1
Overview
Port C is an 8-bit I/O port. Port C has a 14-bit PWM output (PWM0, PWM1) and an address bus
output function. 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 10-12 shows the port C pin configuration.
