RC0 can also be the Timer1 oscillator output or a
Timer1 clock input.
RC1 can also be the Timer1 oscillator input or Capture2
input/Compare2 output/PWM2 output.
RC2 can also be the Capture1 input/Compare1 output/
PWM1 output.
RC3/SCK/SCL
RC4/SDI/SDA
RC5/SDO
RC3 can also be the synchronous serial clock input/

output for both SPI and I C modes.
RC4 can also be the SPI Data In (SPI mode) or
2
data I/O (I C mode).
RC5 can also be the SPI Data Out
(SPI mode).
RC6/TX/CK
RC6 can also be the USART Asynchronous Transmit or
Synchronous Clock.
RC7/RX/DT
RC7 can also be the USART Asynchronous Receive or
Synchronous Data.
PORTD is a bi-directional I/O port or parallel slave port
when interfacing to a microprocessor bus.

Note 1: This buffer is a Schmitt Trigger input when configured as the external interrupt.
2: This buffer is a Schmitt Trigger input when used in Serial Programming mode.
3: This buffer is a Schmitt Trigger input when configured as general purpose I/O and a TTL input when used in the Parallel
Slave Port mode (for interfacing to a microprocessor bus).
4: This buffer is a Schmitt Trigger input when configured in RC oscillator mode and a CMOS input otherwise.
5: A/D is not available on the PIC16C65B.
