Description
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. CMOS otherwise.
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.
PORTA is a bi-directional I/O port.
