Initial IDLE state of the clock does match the MOSI settings

Official Hardware Mega Due

I comunicated the Arduino Due by the SPI bus to a TLV2548 on a PCB that works at 10MHz and needs to recive 3 instructions to access a sensor. It used to work normaly but suddenly and with no evident reason it stoped working. I tried to analyze it with a the Logic 2 program and it gave me that error. The error disapears when I turn the setting to CPOL= 1, but still I can't see that the Arduino is sending the hexadecimals instructions as it supposed to be

Can somebody help me to unterstand what's happening?

The data sheet says CPOL = 0, CPHA = 0. Tell that also your logic analyzer.

Yeah, the datasheet says it like that but it keeps giving me errors.

What's "it"?

Which signals are displayed by which channel?
