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/programming voltage input. This
pin is an active low RESET to the device.
PORTA is a bi-directional I/O port.
Analog comparator input.
Bus activity output. No connection if not used. It is a CMOS-
levels representation of the LIN pin
Analog comparator input or V
Analog comparator input/output.
Can be selected to be the clock input to the Timer0 timer/
counter or a comparator output. Output is open drain type.
PORTB is a bi-directional I/O port. PORTB can be software
programmed for internal weak pull-up on all inputs.
RB0/INT can also be selected as an external interrupt pin.
