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.

RESET OUTPUT CONFIGURATION
00 = RESET is asserted if at least one of the selected inputs exceeds its undervoltage
threshold
01 = RESET is asserted if at least one of the selected inputs exceeds its early warning
threshold
10 = RESET is asserted if at least one of the selected inputs exceeds its overvoltage threshold
11 = RESET is asserted if any of the selected inputs exceeds undervoltage or overvoltage
thresholds
0 = RESET is an active-low output
1 = RESET is an active-high output
0 = RESET is a open-drain output
1 = RESET is an push-pull output

DESCRIPTION
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 21 for RESET depen-
dencies and configuration registers.
