2-Wire-Serial Control Interface
8.7.1
General
There is an I2C slave block implemented to have access to 64 byte of setting information.
The I2C address is: Adr_Group8 - audio processors
8Ch_write
8Dh_read
8.7.2
Protocol
Figure 13. Byte Write
Figure 14. Page Write
Byte Write and Page Write formats are used to write data to the slave.
The transmission begins with the START condition, which is generated by the master when the bus is in IDLE state
(the bus is free). The device-write address is followed by the word address. After the word address any number of data
bytes can be sent to the slave. The word address is incremented internally, in order to write subsequent data bytes on
subsequent address locations.
