FILT of Quadrature Decoder (QDC) cannot be set

[Shuhei_D]

Hello,

I want to set QDC FILT with i.MXRT1170, but even if I set 0xffff to FILT as shown below, I can only set up to 0x7ff.

 

How to set PRSC of FILT?

Hi again @Shuhei_D,

We have confirmed that this is a documentation error. PRSC does not exist in the FILT register on RT1170. The next release of the RM and the SDK will be corrected from this mistake.

Thanks for reporting this issue,
Edwin.

Hi @Shuhei_D,

I was able to replicate this problem on my side. It could be a bug on the Peripherals+ side, on the SDK side, or even an errata on the chip. I will investigate further and come back once I have an answer.

BR,
Edwin.
