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.
I/O - PIO0_0 — General purpose digital input/output pin.
PIO0_1/CLKOUT/
CT32B0_MAT2
-C1

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.
PIO0_6/SCK0 - A1
