Description
Oscillator crystal input/external clock source input.
Oscillator crystal output. Connects to crystal or resonator in
crystal oscillator mode. In RC mode, OSC2 pin outputs
CLKOUT which has 1/4 the frequency of OSC1, and
denotes the instruction cycle rate.
Master clear (reset) input or programming voltage input.
This pin is an active low reset to the device.
PORTA is a bi-directional I/O port.
PORTB is a bi-directional I/O port. PORTB can be software
programmed for internal weak pull-up on all inputs.
P = power
ST = Schmitt Trigger input
RA0 can also be analog input0
RA1 can also be analog input1
RA2 can also be analog input2
RA3 can also be analog input3 or analog reference
voltage
RA4 can also be the clock input to the Timer0 timer/
counter. Output is open drain type.
RA5 can also be analog input4 or the slave select for
the synchronous serial port.
RB0 can also be the external interrupt pin.
