0x58—Bit[3] N_CTS_Disable
This bit makes it possible to prevent the N/CTS packet on the
link from writing to the N and CTS registers.

0x59—Bit[6] MDA/MCL PU Disable
This bit disables the inter MDA/MCL pull-ups.
0x59—Bit[5] CLK Term O/R
This bit allows for overriding during power down. 0 = auto,
1 = manual.
0x59—Bit[4] Manual CLK Term
This bit allows normal clock termination or disconnects it.
0 = normal, 1 = disconnected.
0x59—Bit[2] FIFO Reset UF
This bit resets the audio FIFO if underflow is detected.
0x59—Bit[1] FIFO Reset OF
This bit resets the audio FIFO if overflow is detected.
0x59—Bit[0] MDA/MCL Three-State
This bit three-states the MDA/MCL lines to allow in-circuit
programming of the EEPROM.

0x5A—Bit[6:0] Packet Detect
This register indicates if a data packet in specific sections has
been detected. These seven bits are updated if any specific
packet has been received since last reset or loss of clock detect.
Normal is 0x00.

0x7B—Bits[7:0] CTS (Cycle Time Stamp) (19:12)
These are the most significant 8 bits of a 20-bit word used in the
20-bit N term in the regeneration of the audio clock.
0x7C—Bits[7:0] CTS (11:4)
0x7D—Bits[7:4] CTS (3:0)
0x7D—Bits[3:0] N (19:16)
These are the most significant 4 bits of a 20-bit word used along
with the 20-bit CTS term to regenerate the audio clock.
