LPM Diagnosis

In case an internal error (e.g. ECC) is detected during LPM mode the device sets the WUOUT pin to the high state

(Vhigh_wake) and transmits the LPM diagnosis response as response of next received SPI command.

The sensor is able to provide on SPI request LPM diagnosis information.

Diagnosis Reset

The Reset-bit (C12 for 16-bit commands, C4 for 8-bit commands) of a SPI command allows using different reset

strategies:

•

Reset-bit = '0': All transmitted failures will be reset (with the exception of ECC error)

•

Reset-bit = '1': A transmitted failure will not be reset

Attention: Reset of the ECC error is not possible. Once they are detected and transmitted it remains until supply

reset or power-down mode is entered.
