Polarity
D0: Shutdown - When set to 1 the LM92 goes to low power shutdown mode. Power up default of 0 .
D1: Interrupt mode - 0 is Comparator Interrupt mode, 1 is Event Interrupt mode. Power up default of 0 .
D2, D3: T_CRIT_A and INT Polarity - 0 is active low, 1 is active high. Outputs are open-drain. Power up default
of 0
D4: Fault Queue - When set to 1 the Fault Queue is enabled, see FAULT QUEUE. Power up default of 0 .
D5D7: These bits are used for production testing and must be kept zero for normal operation.
