Part Number: TAS5756M
Hi SIrs,
Same as the TAS5766 Smart Amp discussion at 
We found the following I2C register data mismatch after wrote and read back from the TAS5756 device:
Would you pls provde the TAS5756's I2C register list we can ignore when doing read and write comparison?
reg: Starting address
read: Read back
write: Write data
count : Line number
Number: Multibyte write offset:
