0 No fault

1 Fault

STB

0 Short to Battery

Cleared by SSM_RESET or SPI read or when channel is commanded OFF

via SPI RSCTRL

Not cleared by channel OFF caused by STG or RSTEMP

Set when channel voltage exceeds VSUP for a time greater than TSTBTH

0 No fault

1 Fault

CURRENT_HI

0 Current High

Cleared by SSM_RESET or SPI read or when channel is commanded OFF

via SPI RSCTRL

Set when channel current exceeds ILKGG for a time determined by an

up/down counter

0 No fault

1 Fault

OPENDET

0 Open Sensor Detected

Cleared by SSM_RESET or SPI read or when channel is commanded OFF

via SPI RSCTRL

Set when channel current exceeds ILKGB for a time determined by an

up/down counter

0 No fault

1 Fault

RSTEMP

0 Over temperature detected

Cleared by SSM_RESET or when channel is commanded OFF via SPI

RSCTRL

Set when over-temp condition is detected

0 No fault

1 Fault

INVALID

0 Invalid Data

Cleared by SSM_RESET or SPI read or when channel is commanded OFF

via SPI RSCTRL or if one of the following is set:

STG, STB, CURRENT_HI, OPEN_DET, RSTEMP, SLOT ERROR (PSI5) or if

a new valid data is received.

Set in PSI5 configuration when two valid start bits are received and a

Manchester error (# of bits, bit timing) or parity error is detected

0 No fault

1 Fault

NODATA

1 No Data in buffer
