The status bit Low_Batt is set to “1” if the voltage at pin VSOUT V
(typically 2.38V). Low_Batt is set to “0” if V
via the 4-wire serial interface or N_RESET is set to low.
If V
trol register 3 is “1”, a DVCC_RESET is also generated. If V
connected microcontroller by setting bit VSOUT_EN = 0, no DVCC_RESET is generated.
