2-WIRE SERIAL CONTROL REGISTER DETAIL CHIP IDENTIFICATION
0x00—Bits[7:0] Chip Revision
An 8-bit register that represents the silicon revision.
0x01—Bits[3:0] N[19:16]
These are the most significant four bits of a 20-bit word used
along with the 20-bit CTS term in the receiver to regenerate the
audio clock.
0x02—Bits[7:0] N[15-8]
0x03—Bits[7:0] [(7-0]
0x04—Bits[3:0] CTS_Int[19:16]
These are the most significant four bits of a 20-bit word used
along with the 20-bit N term in the receiver to regenerate the
audio clock. This is the measured or internal CTS. The internal
or external CTS can be selected via R0x0A Bit 7.
0x05—Bits[7:0] CTS_Int[15:8]
0x06—Bits[7:0] CTS_In[7:0]
0x07—Bits[3:0] CT_Ext[19:16])
These are the most significant four bits of a 20-bit word used
along with the 20-bit N term in the receiver to regenerate the
audio clock. This is the external CTS. The internal or external
CTS can be selected via R0x0A Bit 7.
0x08—Bits[7:0] CTS_Ext[15:8]
0x09—Bits[7:0] CTS_Ext[7:0]
0x0A—Bits[7] CTS_Sel
When internal CTS is selected, the CTS is calculated by the
AD9889.

0x0A—Bit[3] MCLK_SP
If MCLK is available for S/PDIF, it is used for bit recovery;
otherwise, internal circuitry is used.
0x0A—Bit[2] MCLK_I
If MCLK is available for I
otherwise, internal circuitry is used.
0x0A—Bits[1:0] MCLK_Ratio

0x0C—Bits[5:2] I
0x0C—Bits[1:0] I
0x0D—Bits[4:0] I
For right-justified audio only. Default is 11000 (24). Not valid
for widths greater than 24.
0x0E—Bits[5:3] SUBPKT0_L_src
Source of audio subpacket 0 (left channel) data. Default
is 000.
