Analog Monitor Pin
The pin AOUT is used to monitor several voltages. For details read chapter
Table 72. Source selector register for multiplexer on analog monitor pin
1) Access via UART service and SPI possible. For write access read the remarks of every bit carefully. In case of hard or soft reset
Table 68. ADC result for the (scaled) voltage on V
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
Table 69. Temperature supervision registers
Table 70. ADC result temperature scan
1) Access via UART service and SPI possible. In case of hard reset the register is reset to the hard reset value.
