Question regarding full register description of STWBC-EP power transmitter chip

[AAmer.2]

Hi,

I'm using STWBC-EP and connected it to my host micro controller through UART. I'd like to retrieve different register values over UART while my device is getting charged over the charger.

One of them registers that I'm interested in is HOST_IF_STATUS. When I read the value of this register I read either F0 when there's no device on the charger or 07 when there's a device on the charger. Based on the application note below on page 8 I cannot find the definition of value "07".

Is there any other document that fully describe all register values for STWBC-EP?

Thanks,
