Input/Output Ports
Port C (High Voltage Port)
To enable either PWM or output compare function the corresponding
DDR bit must be set to 1.
If PWM and timer output compare functions are routed to the same pin,
PC0 and PC4 would be connected to the output compare signal, PC5
would be connected to the PWM signal.
For using the input capture be sure that the PB0IC bit in the I/O
configuration register is set to 0, and the corresponding pin PC0 or PC4
is switched to input mode. PC4 may also be in the ISO9141 compatible
mode.
For using the contact sense function, it is not recommended to route any
special signal to the corresponding pins.
