[TC3XX] Can we use CH29 to read in EVADC using Alias feature ?

Can we use CH29 for EVADC read operation ? 

By configuring Alias register in CH0/CH1

[Di_W]

The Alias feature allows the user to redirect conversion requests for channels 0 and/or 1 to other channel numbers. Using the alias feature, a conversion request for channel 0 or channel 1 leads to a conversion of the analog input channel “x” instead of channel 0 or channel 1.

To use CH29 (Vddk reference signal) for channel 0 or 1 simply set GxALIAS.ALIAS0/1=29 and the successive conversion result on Ch0/1 will contain the Vddk signal level. Channel configuration and result register assignment are chosen in GxCHCTR0/1 (Channel Control Registers).

Hi SivakumarG,

Are you still having issue with this question? As my colleague mentioned, just simply set GxALIAS.ALIAS0/1 to your expected channel number and config the Channel Control Register to save the result to expected place.

For rest of the ADC configuration you could refer to code example:
