CRYSTAL1: This is the input pin to the internal inverting
amplifier. The system clock is from external crystal or
resonator when FOSC[1:0] (CONFIG3[1:0]) are both logic
1 by default.
CRYSTAL2: This is the output pin from the internal
inverting amplifier. It emits the inverted signal of XTAL1.

GROUND: Digital Ground potential.
POWER SUPPLY: Supply voltage Analog AV
operation.
GROUND: Analog Ground potential.
LDO: LDO output pin
Note: It needs to be connected with a 10uF capacitor.
RESET: /RST pin is a Schmitt trigger input pin for
hardware device reset. A “Low” on this pin for 768 clock
counter of Internal RC 22.1184 MHz while 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.
PORT0: Port 0 is an 8-bit four mode output pin and two
mode input. Its multifunction pins are for CTS1, RTS1,
CTS0, RTS0, SPISS1, MOSI_1, MISO_1, and SPICLK1.
P0 has an alternative function as AD[7:0] while external
memory interface (EBI) is enabled.
These pins which are SPISS1, MOSI_1, MISO_1, and
SPICLK1 for the SPI function used.
CTS0/1: Clear to Send input pin for UART0/1
