Hi,

When over temperature condition is occurred, does "SPI operation" work correctly? 

Thanks and best regards,
M.HATTORI.

    Hi Hattori-san,

    SPI operation is not guaranteed when the device is in an over-temperature condition, but it should be able to.  The over-temperature alarm will assert when the device temperature is greater than 150°C.  It is recommended that the device be configured to take immediate action when this condition is met, such as disabling the DC/DC supplies to reduce power dissipation.  The device is also well beyond the specified temperature range at this point.

    Thanks,

    Paul
