7.3.9 RESET pin (pin RESET_PIO0_0)
See Figure 14 for the reset pad configuration. RESET functionality is not available in
Deep power-down mode. Use the WAKEUP pin to reset the chip and wake up from Deep
power-down mode. An external pull-up resistor is required on this pin for the Deep
power-down mode. The reset pin includes a fixed 20 ns glitch filter.
7.3.10 WAKEUP pin (pin PIO0_16)
The WAKEUP pin is combined with pin PIO0_16 and includes a 20 ns fixed 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.
