Using PDB and other timer, together at the same time on K53 family?

[lucacampanale]

Hi,

I have the following problem:

My "software" on a Kinetis K53 family MK53DN512ZCLQ10 implements a DMA driven DAC for audio speaker, using PDB. And so far so good.

The problem occurs when for other stuff I decide to use, at the same time, another K53-timer e.g., FTM or PIT, together with PDB; in this case DMA driven DAC routine doesn't work.

Any idea? Is it possibile that PDB cannot work together with other timer such as FTM or PIT?

What's wrong?

Thank you all !!!

Hi Luca:

Please check on the Errata e4588 on document attached, this could explain this behavior.

Have a nice day,
