The auxiliary ADC has inputs for the power supplies: AVDD (result in AUX_AVDD*), CVDD (result in AUX_CVDD*), DVDD (result in AUX_DVDD*), and TSREF (result in AUX_TSREF*) voltages. The value returned from an ADC conversion for AVDD and CVDD channels is converted to voltage by:
The auxiliary ADC has inputs for several important references for use with diagnostics and during developmental debugging: 0V (result in AUX_ZERO*), REF2 (result in AUX_REF2*), REF3 (result in AUX_REF3*), the AVAO_REF reference (result in AUX_AVAO*), and half of the OVUV reference (1/2 OVUV reference) and the OTUT reference results in AUX_UV_DAC*, AUX_OV_DAC*, AUX_UT_DAC*, and AUX_OT_DAC*, respectively. The value returned from an ADC conversion for these channels (including DVDD) is converted to voltage as shown in Table 5
There is no internal threshold checking of these values. The expectation is that the microcontroller checks that the values are within the appropriate ranges.
The AUX_UV_DAC and AUX_OV_DAC reports 1/2 of the OVUV reference voltage.
