34 SOP0 Hi-Z SOP[2:0] used for factory restore. See Section 9.5.
35 nRESET Hi-Z 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 GPIO from the 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.
36 VBAT_RESET Hi-Z
37 VBAT1 Hi-Z Power supply for the module, must be connected to battery (2.3 V to 3.6 V)
