output/PWM1 output.
RC3 can also be the synchronous serial clock input/
output for both SPI and I
RC4 can also be the SPI Data In (SPI mode) or
data I/O (I
RC5 can also be the SPI Data Out
(SPI mode).
RC6 can also be the USART Asynchronous
Transmit or Synchronous Clock.
RC7 can also be the USART Asynchronous Receive
or Synchronous Data.
