Description
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.
Bi-directional I/O port

Bi-directional I/O port
Bi-directional I/O port
Bi-directional I/O port or external clock input for TMR0.
Output is open drain type.
Bi-directional I/O port can be software programmed for
internal weak pull-up. RB0/INT can also be selected as an
external interrupt pin.
