Bi-directional I/O port/serial programming data/analog input
0. Can be software programmed for internal weak pull-up
and interrupt on pin change. This buffer is a Schmitt Trigger
input when used in serial programming mode.
Bi-directional I/O port/serial programming clock/analog
input 1/voltage reference. Can be software programmed for
internal weak pull-up and interrupt on pin change. This
buffer is a Schmitt Trigger input when used in serial pro-
gramming mode.
Bi-directional I/O port/analog input 2. Can be configured as
T0CKI or external interrupt.
Input port/master clear (reset) input/programming voltage
input. When configured as MCLR, this pin is an active low
reset to the device. Voltage on MCLR/V

during normal device operation. Can be software pro-
grammed for internal weak pull-up and interrupt on pin
change. Weak pull-up always on if configured as MCLR .
This buffer is Schmitt Trigger when in MCLR mode.
Bi-directional I/O port/oscillator crystal output/analog input
3. Connections to crystal or resonator in crystal oscillator
mode (HS, XT and LP modes only, GPIO in other modes).
In EXTRC and INTRC modes, the pin output can be config-
ured to CLKOUT which has 1/4 the frequency of OSC1 and
denotes the instruction cycle rate.
Bidirectional IO port/oscillator crystal input/external clock
source input (GPIO in INTRC mode only, OSC1 in all other
oscillator modes). Schmitt trigger in EXTRC mode only.
