1) Access via UART service and SPI possible. In case of hard reset the register is reset to the hard reset value.
Temperature Supervision Register
The temperature supervision is necessary for protection in case of high power dissipation in failure cases, for ex-
ample short circuit of supply outputs. For details read chapter 8.3 Temperature Supervision.
