FRAME DELAY REGISTERS (0x06, 0x0E)
This register can be used to specify delay in video frames instead of audio samples. When the MSB is set to 1,
the audio delay registers (0x01–0x04) are bypassed and the Frame Delay Register is used to set the delay
based on the frame rate (D6), audio sample rate (D5–D3), and number of frames to delay (D2–D0).
RJ PACKET LENGTH REGISTERS (0x07, 0x0F)
This register is only used in right justified mode. The decimal value of bits [5:0] represents the width of the
useable data in a right justified audio stream. The number of BCLK transitions between LRCLK transitions must
be greater than or equal to the packet length selected in this register. The maximum packet length value is 24
bits. Any setting greater whose numerical value is greater than 24 bits is limited to the maximum 24 bits.

FUNCTION
Left and Right audio is passed to output with no delay.
Left and Right audio is delayed by 1 sample (1/Fs = delay time)
Left and Right audio is delayed by 4095 samples (4095/Fs = delay time)

Default values are in

.
The total audio delay time is calculated by the following formula:
Audio Delay (in samples) = int [# Delay Frames

Audio Sample Rate]
If the result of the formula above is greater than the maximum number of delay samples (4095 for TPA5051),
then the value is limited to this maximum before passing to the delay block.
