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/
ECCP2
(1)
/P2A
(1)
bit 1 ST Input/output port pin, Timer1 oscillator input, Enhanced Capture 2
input/Compare 2 output/PWM 2 output or Enhanced PWM output
P2A.
RC2/ECCP1/P1A bit 2 ST Input/output port pin, Enhanced Capture 1 input/Compare 1 output/
PWM 1 output or Enhanced PWM output P1A.
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: Valid when CCP2MX is set in all devices and in all operating modes (default). RE7 is the alternate assignment
for ECCP2/P2A for all PIC18F6525/6621 devices and PIC18F8525/8621 devices in Microcontroller modes
when CCP2MX is not set; RB3 is the alternate assignment for PIC18F8525/8621 devices in all other operating
modes.
