Hi,

I have configured the USIC1_CH1 with SCTR.WLE=16, SCTR.FLE=30 and CCR.PM=Odd Mode. The Datasheet says that the USIC sends 31 bits and adds 1 Parity bit at the end of the frame (32 Bits).

If I send an even/odd number of bits (4 bytes complete) over the USIC, no parity information will be added in data and no additional clock cycle will be added to the end of the frame. Do I have to configure some more options?

The data is written into the FIFO and TCI informations are not used.

I have the XMC4500 F144K1024 AC EES

Thanks

Hi thk,

Due to the hardware bug, the parity mode is not working.
This is indicated in the Errata sheet USIC_AI.007 where the parity mode cannot be used for SSC protocol.

Hey all,

in addition, this topic is fixed on XMC4400, XMC42/41 and XMC1000 devices. End of this summer there will be a pin, function compatible device to XMC4500 with this issue fixed.

Ok, thank you.

And will then the XMC4700 also released?
