PIO0_16/AD5/
CT32B1_MAT3/IOH_8/
WAKEUP
26 A6 40 53
[6]
I; PU I/O PIO0_16 — General purpose digital input/output pin.
In Deep power-down mode, this pin functions as the
WAKEUP pin with 20 ns glitch filter. Pull this pin HIGH
externally to enter Deep power-down mode. Pull this
pin LOW to exit Deep power-down mode. A
LOW-going pulse as short as 50 ns wakes up the
part.
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 and Deep power-down
mode is not used.
-IAD5 — A/D converter, input 5.
-OCT32B1_MAT3 — Match output 3 for 32-bit timer 1.
- I/O IOH_8 — I/O Handler input/output 8.
