TABLE 10-5: PORTC FUNCTIONS
TABLE 10-6: SUMMARY OF REGISTERS ASSOCIATED WITH PORTC
Name Bit# Buffer Type Function
RC0/T1OSO/T13CKI bit 0 ST Input/output port pin, Timer1 oscillator output or Timer1/Timer3
clock input.
RC1/T1OSI/CCP2
(1)
bit 1 ST Input/output port pin, Timer1 oscillator input or Capture2 input/
Compare2 output/PWM output (when CCP2MX configuration bit is
disabled).
RC2/CCP1 bit 2 ST Input/output port pin or Capture1 input/Compare1 output/
PWM1 output.
RC3/SCK/SCL bit 3 ST RC3 can also be the synchronous serial clock for both SPI and I
2
C
modes.
RC4/SDI/SDA bit 4 ST RC4 can also be the SPI data in (SPI mode) or data I/O (I
2
C mode).
RC5/SDO bit 5 ST Input/output port pin or synchronous serial port data output.
RC6/TX1/CK1 bit 6 ST Input/output port pin, addressable USART1 asynchronous transmit or
addressable USART1 synchronous clock.
RC7/RX1/DT1 bit 7 ST Input/output port pin, addressable USART1 asynchronous receive or
addressable USART1 synchronous data.
Legend: ST = Schmitt Trigger input
Note 1: RB3 is the alternate assignment for CCP2 when CCP2MX is set.
