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.
