PCM1862: SCK output from GPIO1 in Master mode

Hi,
I have a PCM1862 set as master mode, it has its own crystal.

The device is configured as 32bit, so bclk is 64fs and my mclk is generated by the crystal and it is 512fs (24.576Mhz).

I have to driver device that is laking the PLL so I need a mclk output on GPIO1.

I've enabled the mode on GPIO1 to output SCK0 but I'm not getting the full SCK.

Am I missing something?



SCK_XI_SEL is set to 10b
MST_SCK_SRC is set to 0
MST_MODE is set to 1
CLKDET_EN is set to 1

GPIO1_FUNC is set to 11b

Below a dump of some registers:
