Description
PORTC is a bi-directional I/O port.
PORTD is a bi-directional I/O port or parallel slave port
when interfacing to a microprocessor bus.
PORTE is a bi-directional I/O port.
Ground reference for logic and I/O pins.
Positive supply for logic and I/O pins.
These pins are not internally connected. These pins should
be left unconnected.
P = power
ST = Schmitt Trigger input
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 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.
RE0 can also be read control for the parallel slave port,
or analog input5.
RE1 can also be write control for the parallel slave port,
or analog input6.
RE2 can also be select control for the parallel slave
port, or analog input7.
RC0 can also be the Timer1 oscillator output or a
2
C mode).
