Register 6 - Address 0110
This register enables what events are recorded in the nonvolatile fault latch if bit 3 of R5 is cleared. The high
order bits of this register control whether the under and over voltage pins are filtered, and the two low order bits
program the current regulation time period.
Register 7 - Address 0111
This register controls the UV hysteresis. The values shown are with respect to V
SS
.
