I2C to SPI mode change

I'm wondering what timing is allowed to bring the ADAU1701 from I2C to SPI mode?

The datasheet requires to put the CLATCH low 3 times but I found no timing parameters for low and high periods.

I'm looking for:

- min/max distance RESET LOW->HIGH to CLATCH HIGH->LOW

- min/max CLATCH LOW period

- min/max CLATCH HIGH period

to correctly change the I2C to SPI mode.
