ADAU1467 works as SPI master when selfboot is enabled, but how to configure SPI clock frequency for the SPI master?
I tried to look through 1467 datasheet and past EZ threads, but couldn't find it.
I just want to understand how the selfboot function(state machine) works.
As far as I checked with 1467 EVB and SigmaStudio 4.6, Actual SPI clock monitored by a scope
- During Selfboot write : around 10M regardless of "Write Speed" setting,
- Selfboot enabled(read) : around 10k if "Write Speed" was below 1,000k
- Selfboot enabled(read) : around 500k if "Write Speed" was 10,000k
Could you clarify this?
