TLV320DAC3203: Detailed register map for DAC Coefficients Buffer

Hi Satoshi-san,

Section 2.4.2.2 on page 40 from the same document (SLAU434) provides more detail about the values that should be written to coefficient registers.
Buffer A and Buffer B are used when adaptive filtering is enabled. Adaptive filtering use one of the buffers as active and user can write into the non-active buffer, then user can change active buffer from Buffer A to Buffer B or vice versa to perform register changes on the fly.
If you can get an EVM you could use GUI to configure coefficients using the graphic interface, then read back register settings using register table so you can use these setting on a different setup.
