Regarding ADC Result Registers for Piccolo (TMS320F28027)

Other Parts Discussed in Thread: TMS320F28027

Hi All,

I am using the Piccolo TMS320F28027 device and the inbuilt ADC module for my application. I would like to know what happens to the ADC Result Registers once they are read by my application? Are they updated only on next conversion or are they automatically cleared once the application software reads them (as it happens in some other micro controllers).While I could see that they retain their values in the watch window, I didnt find any specific mention of the same in the data sheets. Could someone help with this?

Thanks & Regards,

Hi JD,

You are correct, the results registers hold their value until the next conversion overwrites them.

To determine exactly when they will be overwritten, you can look at the diagrams in the ADC reference guide (spruge5c), section 1.11 - ADC timings.
