I2C registers for serial data channel 2
The control register allows the user to mute a specific audio channel. It is also used to specify the data type (I2S,
Right-Justified, or Left-Justified).

Default values are in bold.
The audio delay for the left and right channels is fixed by writing a total of 13 bits (2 byte transfer) to upper and
lower registers as specified in Table 1. A multiple byte transfer should be performed starting with the control
register and following with 4 bytes to fill the upper and lower registers associated with right/left channel delay.
The decimal value of D0–D13 equals the number of samples to delay. The maximum number of delayed
samples per channel is 4095 for the TPA5051. This equates to 85.3 ms ([4095
× (1/Fs)] at 48 kHz) of delay per
channel.
