MFR_PWRGD_EN
This command register controls the mapping of power
good status to the power good pin. Note that odd num-
bered channels whose ADC is in high res mode do not
contribute to power good.

OPERATION
Read only, always returns 0s.
Watchdog
1 = Watchdog timer not-expired status is ANDed with PWRGD status for any similarly enabled channels to
determine when the PWRGD pin gets asserted.
0 = Watchdog timer does not affect the PWRGD pin.
Channel 7
1 = PWRGD status for this channel is ANDed with PWRGD status for any similarly enabled channels to determine
when the PWRGD pin gets asserted.
0 = PRWGD status for this channel does not affect the PWRGD pin.
Channel 6
1 = PWRGD status for this channel is ANDed with PWRGD status for any similarly enabled channels to determine
when the PWRGD pin gets asserted.
0 = PRWGD status for this channel does not affect the PWRGD pin.
Channel 5
1 = PWRGD status for this channel is ANDed with PWRGD status for any similarly enabled channels to determine
when the PWRGD pin gets asserted.
0 = PRWGD status for this channel does not affect the PWRGD pin.
Channel 4
1 = PWRGD status for this channel is ANDed with PWRGD status for any similarly enabled channels to determine
when the PWRGD pin gets asserted.
0 = PRWGD status for this channel does not affect the PWRGD pin.
Channel 3
1 = PWRGD status for this channel is ANDed with PWRGD status for any similarly enabled channels to determine
when the PWRGD pin gets asserted.
0 = PRWGD status for this channel does not affect the PWRGD pin.
Channel 2
1 = PWRGD status for this channel is ANDed with PWRGD status for any similarly enabled channels to determine
when the PWRGD pin gets asserted.
0 = PRWGD status for this channel does not affect the PWRGD pin.
Channel 1
1 = PWRGD status for this channel is ANDed with PWRGD status for any similarly enabled channels to determine
when the PWRGD pin gets asserted.
0 = PRWGD status for this channel does not affect the PWRGD pin.
Channel 0
1 = PWRGD status for this channel is ANDed with PWRGD status for any similarly enabled channels to determine
when the PWRGD pin gets asserted.
0 = PRWGD status for this channel does not affect the PWRGD pin.
