I need more information about FDA803S on website there aren't document explaining I2C registers and details about connection of configurable pins (eq ENABLE1 an 2)

There is a firmware example for use this device connected to a stm32 microcontroller?

The FDA803S is a class-D amplifier for automotive applications. As the STM32 are not currently certified for automotive use, there is no support for them at this time. For more information about this amplifier, please discuss the matter with your preferred distributor.
