Remote sensor SPI tables

A summary of all the registers contained within the remote sensor SPI map is shown below and is referenced

throughout the specification they apply to. The SPI register tables also specify the effect of the internal reset

signals assertion on each bit field.

Note:

The symbol ‘-‘ is used to indicate that the register is not affected by the relevant reset signal.

6.6.1

Remote sensor SPI global status word

The remote sensor SPI contains an 11-bit word that returns global status information. The Global Status Word

(GSW) of the remote sensor SPI is the most significant 11 bits of MISO_RS data.

MISO_RS GSW

Name

POR WSM SSM

Description

SPIFLT

SPI Fault, set if previous SPI frame had wrong parity check or wrong number of bits,

cleared upon read

0: No fault

1: Fault

Unused

RSFLT

Remote sensor Interface Fault Present, logical OR of the corresponding FLTBIT bits in

RSDRx (bit 15) for all faults but NODATA

0: All the RSDRx-FLTBIT bits are 0

1: At least one of the RSDRx-FLTBIT bits is 1 and the associated fault code is different

from NODATA

Unused

ERR_RID

Read address received in the actual SPI frame is unused so data in the response is don't

care

0: No Error

1: Error
