channel swap in TDM mode BF607

hi !

is there any known option/behaviour for the SPORT interface in TDM mode.

I have the effect that CH1 input is "routed" to CH5

CH2->CH6

CH3->CH7

CH4->CH8

CH5_>CH1 ....

 

but the hardware is correct ! So maybe DSP or the used DAC swap the channels.

but I couldn't find any information. the 8channel ADC receives the channels in correct order - I copy these to the output buffer (DMAmode) and then

 

MCTL is configured : WSIZE = 7 (Nr.of channels-1)

MFD=1

WOFFSET=0

 

 

I use a cirrus CS4385 DA-converter (8channels)

 

regards chris
