Description
Oscillator input in crystal/resonator or RC oscillator mode.
External clock input in external clock mode.
oscillator mode. In RC oscillator or external clock modes
OSC2 pin outputs CLKOUT which has one fourth the fre-
quency (F
rate.
Master clear (reset) input or Programming Voltage (V
input. This is the active low reset input to the chip.
PORTA is a bi-directional I/O Port except for RA0 and RA1
which are input only.
PORTB is a bi-directional I/O Port with software config-
urable weak pull-ups.
Oscillator output. Connects to crystal or resonator in crystal
RA0 can also be selected as an external interrupt
input. Interrupt can be configured to be on positive or
negative edge.
RA1 can also be selected as an external interrupt
input, and the interrupt can be configured to be on pos-
itive or negative edge. RA1 can also be selected to be
the clock input to the Timer0 timer/counter.
RA2 can also be used as the slave select input for the
SPI or the clock input for the I
High voltage, high current, open drain input/output port
pin.
RA3 can also be used as the data input for the SPI or
the data for the I
High voltage, high current, open drain input/output port
pin.
RA4 can also be selected as the USART1 (SCI) Asyn-
chronous Receive or USART1 (SCI) Synchronous
Data.
RA5 can also be selected as the USART1 (SCI) Asyn-
chronous Transmit or USART1 (SCI) Synchronous
Clock.
RB0 can also be the Capture1 input pin.
RB1 can also be the Capture2 input pin.
RB2 can also be the PWM1 output pin.
RB3 can also be the PWM2 output pin.
RB4 can also be the external clock input to Timer1 and
Timer2.
RB5 can also be the external clock input to Timer3.
RB6 can also be used as the master/slave clock for the
SPI.
RB7 can also be used as the data output for the SPI.
