MPC5644 Decimation Filter for 8th FIR

kadiraktas — Tue, 18 Apr 2017 13:12:19 GMT

Hi,

I am using MPC5644A. I couldn't use decimation filter with ADC. I couldn't use outputs of ADC to inputs of Decimation Filter Block. I'm trying to use normal mode and 8th FIR. Can anyone help me?

I have already read but couldn't find anything to help me. But I am going to read it again.

In additon, noticed that I can't use ADC_ACR register properly.

If you have different documents or examples, please send me.
