Figure 1 - 11. Alignment of 5.23 Coefficient in 32-Bit I2C Word
Two 32-bit words must be sent over the I2C bus to download a level or threshold coefficient into the TAS5028.
The alignment of the 48-bit, 25.23 formatted coefficient in the 8-byte (two 32-bit words) I2C word is shown in
Figure 1 - 12.
