This pin is the input to the onboard crystal
oscillator for the primary system clock.
If an external oscillator is used, its clock
output should be connected to this pin.
When a crystal is used, it should be
connected between X
This pin is the output of the onboard

Power Supply.
This pin can be used for GPIO. It can be
individually programmed as input or
output and can also be used individually
as an interrupt input. Each Port B pin,
when programmed as output, can be
selected to be an open-drain or open-
source output.
Alternate clock source for Programmable
Reload Timers 0 and 2. This signal is
multiplexed with PB0.
