Description
These pins should be left
unconnected
Master clear (RESET) input. This pin is
an active low RESET to the device.
Programming voltage input
Oscillator crystal input or external
clock source input. ST buffer when
configured in RC mode. Otherwise
CMOS.
External clock source input. Always
associated with pin function OSC1
(see OSC1/CLKI, OSC2/CLKO pins).
Oscillator crystal output.
Connects to crystal or resonator in
Crystal Oscillator mode.
In RC mode, OSC2 pin outputs CLKO,
which has 1/4 the frequency of OSC1
and denotes the instruction cycle rate
General purpose I/O pin
