regarding TDA5240 first data output abnormal.

[Weili]

Hi Sir,

Our company is a manufacturer of RF modules.

We did a new module to replace TDA5210.

So we used the TDA5240 DK board for testing.

And now there is a problem when the first data is fetched, his Pulse width is inconsistent with tda5210. 

below is our waveform picture

SPI setting as an attachment file.

could you help me?
