ARMSELx

00 ARMINT select for safing record x - correlates A

Updated by SSM_RESET or SPI write while in DIAG state

00 ARMP OR ARMN

01 ARMP

10 ARMN

11 ARMP OR ARMN

SPIFLDSELx

SPI field select for safing record x - determines which 16-bit field in long

SPI messages (>31 bit) to use for response on MISO of SPI monitor.

In case of messages less than 32 bits this bit is don't care. Updated by

SSM_RESET or SPI write while in DIAG state.

0 First 16 bits of SPI MISO frame used for Response Mask and Data

Mask bit-wise AND

1 Last 16 bits of SPI MISO frame used for Response Mask and Data

Mask bit-wise AND

LIM SELx

Data range limit select for safing record x - When enabled, determines

the range limit used for incoming sensor data

Updated by SSM_RESET or SPI write while in DIAG state

0 8-bit data range limit - incoming |data| >120d is not recognized as

valid data

1 10-bit data range limit - incoming |data| > 480d is not recognized as

valid data

LIM Enx

Data range limit enable for safing record x

Updated by SSM_RESET or SPI write while in DIAG state

0 Data range limit disabled

1 Data range limit enabled

COMBx

000

Combine function enable for safing record x

Updated by SSM_RESET or SPI write while in DIAG state
