RESET Deassertion
After any MON_ inputs assigned to Slot 12 exceed their
undervoltage thresholds, the reset timeout begins. When
the reset timeout completes, RESET deasserts. The reset
timeout period is set in r19h[6:4]. See Table 21.
Power-Down
Power-down starts when EN is pulled low or the
Software Enable bit is set to ‘1.’ RESET asserts as soon
as power-down begins regardless of the reset output
dependencies. Power down EN_OUT_s simultaneously
or in reverse sequence mode by setting the Reverse
Sequence bit (r54h[4]) appropriately. In reverse
sequence mode (r54h[4] set to ‘1’), the EN_OUT_s
assigned to Slot 11 deassert, the MAX16047/MAX16049
wait for the Slot 11 sequence delay and then proceed
to Slot 10, and so on until the EN_OUT_s assigned to
Slot 0 turn off. When simultaneous power-down is
selected (r54h[4] set to ‘0’), all EN_OUT_s turn off at the
same time.
