Digital monitoring registers
The measurement values are scaled to limit them below the supply voltage (V33I) of the ADC and analog to digi-
tal converted. For scaling values look at chapter Electrical Charecteristics section
Table 63. Voltage supervision registers
Table 64. Mean value for V
1) Access via UART service and SPI possible. In case of hard reset the register is reset to the hard reset value.
Table 65. 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.
Table 66. 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.
Table 67. ADC result for the (scaled) voltage on pin V
1) Access via UART service and SPI possible. In case of hard reset the register is reset to the hard reset value.
