DESCRIPTION
1
NC
Hi-Z
N/A
Unused; leave unconnected.
2
nHIB
Hi-Z
I
Hibernate signal input to the NWP (active low).
This is connected to the MCU GPIO. If the
GPIO from the MCU can float while the MCU
enters low power, consider adding a pull-up
resistor on the board to avoid floating.

For forced AP mode, pull to high on the board
using 100k resistor. Otherwise, pull down to
ground using 100k resistor.⁽¹⁾
