I
ST/CMOS 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.
ST
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.
ST
Analog comparator input
ST
Analog comparator input
ST
Analog comparator input or V
ST
Analog comparator input /output
ST
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.
