ETPU Pad Configuration

I'm using a MPC5554 and more specifically the ePTU onboard. But I have some problems with the PAD configuration. In the documentation, I find that eTPU pads had to be set through SIU_PCR registers. Fore eTPU, these registers are from 113 to 178.

I set PCR register for channels on eTPU A to 0x0C00 in order to set pads to their primary function (eTPU A).

After configuring PCR registers, I download microcode into eTPU. I configure active channels. But, no signal appears on these pads.

Hava you any more information about this issue.

Thank you for your help.
