PCM5122: Internal PLL clock output from GPIO pin

Hello,

We plan to use PCM512x as I2S slave mode without SCK input.

Then internal PLL generate SCK using BCK input as PLL reference, automatically.

This time we need SCK output from GPIO1 pin of PCM512x.

Related register would be Page 0 / Register 80 / G1SL[4:0] 010000: PLL Output/4 (Requires Clock Flex Register)

If PLL clock is 2048fs, GPIO1 output is 512fs as SCK for external DSP etc.

Is that correct assumption of PCM512x function?

Regards,
