8.2.56 ADC Single Measurement - Read (63h)

This command is used to read a single channel of the TPS99000-Q1 ADC. This cannot be performed while video is displaying. While video is displaying, ADC capture is specified by a sequence-aligned look-up table each frame.

The returned ADC measurement is a converted and scaled voltage value in two's complement integer format. The measurement values from all TPS99000-Q1 channels except for channel 0 are represented on a 1mV scale. Channel 0 is represented on a 10µV scale due to its higher gain.

Command Parameters

Return Parameters

Table 8-65 ADC Single Measurement Return Parameters
BYTEBITSDESCRIPTION
2:115:0ADC Measurement

LSByte = Byte 1

Two's complement integer format. All TPS99000-Q1 ADC channels will be reported on a 1-mV scale, except for channel 0 which is reported on a 10-µV scale.

37:4Reserved
3:0ADC Measurement Error Bits

b1xxx = Parity error for this measurement. All other bits and measurement value should be considered invalid.

b0001 = ADC value saturated at maximum value

b0010 = ADC value underflow at minimum value

b0011 = ADC timing error (measurements were triggered too close together)

b0100 = Previous measurement mismatch error

b0101 = Previous measurement parity error

b0110 = Previous measurement stop bit error

b0111 = Input ADC received mismatch error
