Hi,
I want to configure my TAS5717 in BD PWM mode.What are all registers should I update?. Please help me with the value of 0x05,0x20,and 0x25.

Hi, Safeer,
You need to update only register 0x20 to configure the output PWM channels in BD mode, this is done via bit 23 for channel-1 and bit 19 for channel-2. So, you need to write 0x00 89 77 72 to register 0x20. Also, we recommend to use the Inter channel delay (ICD) settings for BD mode from the table of page 47 of the datasheet.

Hi, Safeer,
The mention of register 0x25 may be a typo, and should be 0x20. For this device, the only register that should be changed to configure the PWM outputs on AD or BD mode is register 0x20.
Register 0x25 is used to mux the PWM outputs to the desired output of the amplifier. You may keep the default values so Channel-1 output is in Out_A and Out_B, while Channel-2 output will be in Out_C and Out_D.
