FLT=1: Fault Status

Cleared when all of the following bits are '0': STG, STB, CURRENT_HI, OPENDET, RSTEMP,

NODATA, INVALID, SLOT ERROR, PULSE OVERFLOW ERROR

Set when any of the following bits are '1': STG, STB, CURRENT_HI, OPENDET, RSTEMP,

NODATA, INVALID, SLOT ERROR, PULSE OVERFLOW ERROR

0: No fault

1: Fault

[14]

On/Off: Channel on/off status

Cleared by SSM_RESET or when channel is commanded OFF via SPI RSCTRL or when the STG

bit is set or the RSTEMP bit is set

Set when channel is commanded ON by SPI RSCTRL

0: Off

1: On
