Type
ST/CMOS Oscillator crystal input or external clock source
input.
Oscillator crystal output. Connects to crystal or reso-
nator 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 or 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 or comparator output.
ST
Can be selected to be the clock input to the
Timer0 timer/counter or a comparator output.
Output is open drain type.
ST
PORTB is a bi-directional I/O port. PORTB can be
software programmed for internal weak pull-ups on
all inputs.
