Page 0 / Register 8: Audio Serial Data Interface Control Register A
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 R/W 0 Bit Clock Directional Control
0: Bit clock is an input (slave mode)
1: Bit clock is an output (master mode)
D6 R/W 0 Word Clock Directional Control
0: Word clock is an input (slave mode)
1: Word clock is an output (master mode)
D5 R/W 0 Reserved. Only write zero this bit.
D4 R/W 0 Bit/ Word Clock Drive Control
0: Bit clock and word clock will not be transmitted when in master mode if DAC is powered down
1: Bit clock and word clock will continue to be transmitted when in master mode, even if DAC is
powered down
D3 R/W 0 Reserved. Only write zero to this bit.
D2 R/W 0 3-D Effect Control
0: Disable 3-D digital effect processing
1: Enable 3-D digital effect processing
D1-D0 R/W 00 Reserved. Only write zeroes to these bits.
Page 0 / Register 9: Audio Serial Data Interface Control Register B
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 D6 R/W 00 Audio Serial Data Interface Transfer Mode
00: Serial data bus uses I
2
S mode
01: Serial data bus uses DSP mode
10: Serial data bus uses right-justified mode
11: Serial data bus uses left-justified mode
D5 D4 R/W 00 Audio Serial Data Word Length Control
00: Audio data word length = 16-bits
01: Audio data word length = 20-bits
10: Audio data word length = 24-bits
11: Audio data word length = 32-bits
D3 R/W 0 Bit Clock Rate Control in master mode only
This register only has effect when bit clock is programmed as an output
0: Continuous-transfer mode used to determine master mode bit clock rate
1: 256-clock transfer mode used, resulting in 256 bit clocks per frame
D2 R/W 0 DAC Re-Sync
0: Don t Care
1: Re-Sync Stereo DAC with Digital Interface if the group delay changes by more than DACFS/4.
D1 R/W 0 Reserved. Only write zero to this bit.
D0 R/W Re-Sync Mute Behavior
0: Re-Sync is done without soft-muting the channel. (DAC)
1: Re-Sync is done by internally soft-muting the channel. (DAC)
