We need to configure SDATA OUT0 Port as slave. Hence, we need to configure ASRC for this output Port to sync with the external clock.

Please confirm the output rate setting for this requirement.

'Use rate of serial out 0'

'or'

'Use DSP core START_PULSE rate'

Hello,

If the serial output port 0 is slaved from an external clock, then use 'serial out 0' in the ASRC window. Remember that this is at the output side and the processing is done at the rate of what the start pulse is set for.

Regards,
