The reset output, RESET, is asserted during power-
up/power-down and deasserts following the reset time-
out period once the power-up sequence is complete.
The power-up sequence is complete when any MON_
inputs assigned to Slot 12 exceed their undervoltage
thresholds. If no MON_ inputs are assigned to Slot 12,
the power-up sequence is complete after the slot
sequence delay is expired.

DESCRIPTION
is an active-low output
is an active-high output
is an open-drain output
is a push-pull output
is asserted if at least one of the selected inputs exceeds its undervoltage
is asserted if at least one of the selected inputs exceeds its early warning
is asserted if at least one of the selected inputs exceeds its overvoltage
is asserted if any of the selected inputs exceeds undervoltage or overvoltage
RESET
RESET is a configurable output that monitors selected
MON_ voltages during normal operation. RESET also
depends on any monitoring input that has one or more
critical fault enable bits set. Use r19h[1:0] to configure
RESET to assert on an overvoltage fault, undervoltage
fault, or both. Use r19h[3:2] to configure RESET as an
active-high/active-low push-pull/open-drain output. If
desired, configure GPIO4 as a manual reset input, MR,
and pull MR low to assert RESET. RESET includes a
programmable timeout. See Table 27 for RESET depen-
dencies and configuration registers.
