O
—
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.

I/O = Input/Output
TTL = TTL input
P = power
ST = Schmitt Trigger input
Note 1:
This buffer is a Schmitt Trigger input when configured as the external interrupt.
This buffer is a Schmitt Trigger input when used in serial programming mode.
This buffer is a Schmitt Trigger input when configured in RC oscillator mode and a CMOS input otherwise.
