Description:

Default value:

000

R/W

[15] RESERVED

[14] FSIDM: Force SID mismatch

0: NOP

1: the behavior of the MUX which selects SID, CRC/parity and Number of bits, is changed

according to the following table:

slot1 <-->slot2

slot3<-->slot4

slot6<-->slot5

[13] FTSIDM: Force TSID mismatch

0: NOP

1: the behavior of MUX that selects sensor data (and SID) for each time slot is modified in this

way:

– slot2 sensor data -> slot1 sensor data

– slot4 sensor data ->slot3 sensor data

– slot6 sensor data ->slot5 sensor data

Sensor data of time slots 1, 3 and 5 keep a buffer empty value.

[12:6] RESERVED

[5] ACCT: Abort cross-coupling test

0: NOP

1: Stop cross-coupling test immediately

[4:3] SCCT: Start cross-coupling test

11: ignored

00: ignored

01: start cross-coupling test in master mode

10: start cross-coupling test in slave mode

[2:1] RESERVED

[0] TBEC: Test buffer empty check

0 : after a read operation 1F0 is written into the buffer (normal operation)

1 : after a read operation old data are left In the buffer
