PRODUCTION DATA
If the high-side supply (AVDD) is missing, the device provides a constant bitstream of logic 0's at the output, and DOUT is permanently low. Figure 6-6 shows a timing diagram of this process. A one is not generated every 128 clock pulses, which differentiates this condition from a valid negative fullscale input. This feature helps identify high-side power-supply problems on the board. See the Diagnosing Delta-Sigma Modulator Bitstream Using C2000™ Configurable Logic Block (CLB) application note for code examples of diagnosing the digital bitstream.
