0x58—Bits[6:4] MCLK PLL_N

These bits control the division of the MCLK out of the PLL.

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.

0x58—Bit[2:0] MCLK fs_N

These bits control the multiple of 128 fS used for MCLK out.

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.

0x62—Bits[3:0] Word Length

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.
