When the system oscillator is not used, connect XTALIN and XTALOUT as follows: XTALIN can be left floating or can be grounded
(grounding is preferred to reduce susceptibility to noise). XTALOUT should be left floating.

Description
Port 0 — Port 0 is a 12-bit I/O port with individual direction and
function controls for each bit. The operation of port 0 pins depends on
the function selected through the IOCONFIG register block.
RESET — External reset input with 20 ns glitch filter. A LOW-going
pulse as short as 50 ns on this pin resets the device, causing I/O ports
and peripherals to take on their default states and processor execution
to begin at address 0.
PIO0_0 — General purpose digital input/output pin with 10 ns glitch
filter.
PIO0_1 — General purpose digital input/output pin. A LOW level on
this pin during reset starts the ISP command handler.
CLKOUT — Clock out pin.
CT32B0_MAT2 — Match output 2 for 32-bit timer 0.
PIO0_2 — General purpose digital input/output pin.
SSEL0 — Slave select for SPI0.
CT16B0_CAP0 — Capture input 0 for 16-bit timer 0.
PIO0_3 — General purpose digital input/output pin.
PIO0_4 — General purpose digital input/output pin (open-drain).
SCL — I

PIO0_5 — General purpose digital input/output pin (open-drain).
SDA — I

PIO0_6 — General purpose digital input/output pin.
SCK0 — Serial clock for SPI0.
PIO0_7 — General purpose digital input/output pin (high-current
output driver).
CTS — Clear To Send input for UART.
PIO0_8 — General purpose digital input/output pin.
MISO0 — Master In Slave Out for SPI0.
CT16B0_MAT0 — Match output 0 for 16-bit timer 0.
PIO0_9 — General purpose digital input/output pin.
MOSI0 — Master Out Slave In for SPI0.
CT16B0_MAT1 — Match output 1 for 16-bit timer 0.
SWCLK — Serial wire clock.
PIO0_10 — General purpose digital input/output pin.
SCK0 — Serial clock for SPI0.
CT16B0_MAT2 — Match output 2 for 16-bit timer 0.
