DSP Core not run

Dear,

I have already used the ADAU1452 DSP in several designs. But , for a new design I have a problem with the DSP core.

I am using SPI communication to the DSP slave comms port and I try to read registrer from sigmastudio windows Read/Write, so I validate the communication BUS.

When I enable CLKOUT it's work and in Master mode the serial ports generate LRCK and SCLK.

But when I want drive a simple GPO, I never work:

All power supply and Reset are OK.
