Oscillator crystal input/external clock source input.
—
Oscillator crystal output. Connects to crystal or resonator in
crystal oscillator mode. In RC mode, the 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.

RA4 can also be the clock input to the Timer0 module.
Output is open drain type.
RA5 can also be analog input 4 or the slave select for the
synchronous serial port.
PORTB is a bi-directional I/O port. PORTB can be software
programmed for internal weak pull-up on all inputs.
RB0 can also be the external interrupt pin.

PORTC is a bi-directional I/O port.
RC0 can also be the Timer1 oscillator output or Timer1
clock input.
RC1 can also be the Timer1 oscillator input.
RC2 can also be the Capture1 input/Compare1 output/
PWM1 output.

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.
The A/D module is not available on the PIC16C62B.
