Remote sensor SPI read/write registers

7.7.1

Remote sensor data/fault registers (RSDRx @FLT = 0)

Note:

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

divided into two groups (Section 7.7.1 and Section 7.7.2).

Remote Sensor Data and Fault Flag Register ch 0, slot 1 (RSDR0)

Remote Sensor Data and Fault Flag Register ch 1, slot 1 (RSDR1)

Remote Sensor Data and Fault Flag Register ch 0, slot 2 (RSDR4)

Remote Sensor Data and Fault Flag Register ch 1, slot 2 (RSDR5)

Remote Sensor Data and Fault Flag Register ch 0, slot 3 (RSDR8)

Remote Sensor Data and Fault Flag Register ch 1, slot 3 (RSDR9)

Bit 15 = 0 NO FAULT Condition

CRC

LCID [3:0]

DATA [9:0]

CRC[2:0]

- CRC based on bits [16:0]

Updated based on bits [16:0]

FLT

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, INVALID, SLOT_ERROR, NODATA
