11.1.8. Serial Message Error Code

The list of error and status messages transmitted in the 12-bit Serial Message data field when Serial

Message 8-bit ID is 0x01, is given in the Table 44. The error is one-hot encoded and therefore each bit is

linked to one or several monitor. Only the first error detected is reported and serial message error code

will not be updated until all the errors have disappeared. This mechanism ensures only one error at a

time takes control of the error debouncing counter (see 13.5.2).

The MSB acts as an error Flag when SENT_DIAG_STRICT is set. This bit will be high only when an error is

present. For compatibility with previous Triaxis®, this bit can be kept high even if no error is present

(SENT_DIAG_STRICT = 0).
