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/
bit 1
ST
Input/output port pin, Timer1 oscillator input, Enhanced Capture 2
ECCP2⁽¹⁾/P2A⁽¹⁾
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
RC4/SDI/SDA
bit 3
ST
RC3 can also be the synchronous serial clock for both SPI™ and
I²C™ modes.
bit 4
ST
RC4 can also be the SPI data in (SPI mode) or data I/O (I²C 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.

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.
