MFR_PWRGD_EN
This command register controls the mapping of the watchdog and channel power good status to the PWRGD pin. Note
This command register controls the mapping of the watchdog and channel power good status to the PWRGD pin. Note
that odd numbered channels whose ADC is in high res mode do not contribute to power good.
