Bi-directional I/O port. Can be configured as T0CKI.
Input port/master clear (reset) input/programming volt-
age input. When configured as MCLR, this pin is an
active low reset to the device. Voltage on MCLR/V
must not exceed V

up always on if configured as MCLR
Bi-directional I/O port/oscillator crystal output. Con-
nections to crystal or resonator in crystal oscillator
mode (XT and LP modes only, GPIO in other modes).
clock source input (GPIO in Internal RC mode only,
OSC1 in all other oscillator modes). TTL input when
