16 XTAL1
CRYSTAL1: This is the input pin to the internal inverting
I _{amplifier. The system clock is from external crystal or}
(ST) ^{resonator when FOSC[1:0] (CONFIG3[1:0]) are both logic}
1 by default.

15 XTAL2
O
CRYSTAL2: This is the output pin from the internal
inverting amplifier. It emits the inverted signal of XTAL1.

/RST
RESET: /RST pin is a Schmitt trigger input pin for
hardware device reset. A “Low” on this pin for 768 clock
I counter of Internal 22.1184 MHz high speed oscillator while
(ST) the system clock is running will reset the device. /RST pin
has an internal pull-up resistor allowing power-on reset by
simply connecting an external capacitor to GND.
