I just tried a simple ADC conversion using MPC5643L controller with overwrite enabled and overwrite disabled.In both cases, I am able to view the changes in the converted data of the analog channels (CDRn) registers.As I vary the input voltage, the corresponding data is monitored in both cases.
I just want to know the difference between ADC measurement with overwrite enabled and overwrite disabled?
As far as I know, Overwrite enable will helps to overwrite the old conversion results with the new one.But in my case,
for both overwrite enabled and disabled, New results are getting updated.Whether I understood correctly?
Can anyone explain with an example?
what is the impact of having overwrite in ADC?
Kindly answer my question. I know its a simple one. But I want to know the use case of overwrite.
