Decimation Filter

[Varshap]

Hi

I am trying to configure decimation filter in cascaded mode, basic configurations for Block A , B are done. ADC triggered base. I have configure ACR1 to send ADC results to filter block instead of RFIFO, conversion command is updated with alternate configuration commands as per ACR1. still I am not able to see any values in TAP registers. what could be the miss. please help me here.

There is an application note for this purpose form MPC5674F device:

I have tried decimation filter with following example code, performing only simple integrator functionality just for example purposes. Mainly it could help you to understand how to configure eQADC, decimation filter, eTPU and their relation. Prepared for MPC5676R:

Actually you have not specified used device.

Hope it helps
