Description
PIO0_0 to PIO0_11 I/O 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
/PIO0_0 3
[2]
C1
[2]
yes I I; PU 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.
In deep power-down mode, this pin must be pulled
HIGH externally. The RESET
pin can be left
unconnected or be used as a GPIO pin if an external
RESET
function is not needed.
I/O - PIO0_0 — General purpose digital input/output pin with
10 ns glitch filter.

yes I/O I; PU PIO0_1 — General purpose digital input/output pin. A
LOW level on this pin during reset starts the ISP
command handler.
O-CLKOUT — Clockout pin.
O-CT32B0_MAT2 — Match output 2 for 32-bit timer 0.
