nRESET
I
32
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 pull-
up resistor a leakage current of 3.3 V / 100 kΩ is expected.
