Remote sensor data/fault registers w/o fault (RSDRx)

Remote sensor 0 data and fault flag register (RSDR0)

Remote sensor 1 data and fault flag register (RSDR1)

Note:

The value in Bit15 (FLT) will re-define the use of the other bits, hence the information below

is divided into two groups.

Bit 15 = 0 NO FAULT condition

Address:

50 (RSDR0)

51 (RSDR1)

Type:

Buffer:

$5000 (RSDR0)

$5100 (RSDR1)

FLT 1

1 Fault Status - Depending on Fault Status, the DATA bits are defined differently

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

OPENDET, RSTEMP, NODATA

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

OPENDET, RSTEMP, NODATA

0 No fault

1 Fault

On/Off 0

0 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
