HIGH LEVEL COMMAND INTERFACE
The I2C-bus interface is used to pass control commands and data between the SAA526xPS and the television
microcontroller. The interface uses high level commands, which are backward compatible with the SAFARI interface.
The formats for the I2C-bus transmission are as follows:
