Function
Reserved
Controls the reset output at pin 17
(QGPO) when Reset mode is
selected (OEMCFG3-7 set to 1)
Operation
Read-only; these bits always return 00000.
By default, these three bits are 000, and the QGPO output
is undriven.
If RESET mode is selected in OEMCFG3:
When the three bits are written to 111, QGPO’s open-drain
output will be driven low for 125 μs (typical), after which
QGPO reenters the undriven state.
The RESETOUT field is cleared from 111 to 000 22.5 ms
(typical) after the deassertion edge of QGPO. Other values
of this delay may be selected in the TRSTCLR[2:0] field in
OEMCFG2.
If Reset mode in OEMCFG3 is not selected, these three
bits have no function.
