WAKEUP

40[5]

I/O

I; PU

PIO1_4 — General purpose digital input/output pin with 10 ns

glitch filter.

I-

O-

CT32B1_MAT3 — Match output 3 for 32-bit timer 1.

I-

WAKEUP — Deep power-down mode wake-up pin with 20 ns

glitch filter. This pin must be pulled HIGH externally to enter

Deep power-down mode and pulled LOW to exit Deep

power-down mode. A LOW-going pulse as short as 50 ns

wakes up the part.
