external 10 kω resistor is required to pull this pin high. see
section 6.11.1 for sop[2:0] configuration modes.

nreset

i

there is an internal, 100 kω, pull-up resistor option from the
nreset pin to vbat_reset. note: vbat_reset is not
connected to vbat1 or vbat2 within the module. the following
connection schemes are recommended:
• connect nreset to a switch, external controller, or host,
only if nreset will be in a defined state under all operating
conditions. leave vbat_reset unconnected to save
power.
• if nreset cannot be in a defined state under all operating
conditions, connect vbat_reset to the main module
power supply (vbat1 and vbat2). due to the internal pullup
resistor a leakage current of 3.3 v / 100 kω is expected.
