Clear Mask

WM5102 does not fully support this function.

The CM bytes of the REQUEST_CLEAR_INFORMATION or

CLEAR_INFORMATION messages must not be sent to WM5102

Devices. When either of these messages is received, all bits

within the specified Information Slice will be cleared.

Data Length

Data Type

WM5102 supports the following DT codes:

0h - Not indicated

1h - LPCM audio

Note that 2’s complement PCM can be supported with DT=0h.

Information Slice

Logical Address

LAIF

Logical Address, Incoming Framer

NCi

Number of Incoming Framer Clock Cycles

NCo

Number of Outgoing Framer Clock Cycles

Port Number

Note that the Port Numbers of the WM5102 SLIMbus paths are

Presence Rate

Note that the Presence Rate must be the same as the Sample

Rate selected for the associated WM5102 SLIMbus path.

Root Frequency

WM5102 supports the following RF codes as Active Framer:

1h - 24.576MHz

2h - 22.5792MHz

All codes are supported when WM5102 is not the Active Framer.

Restart Time

WM5102 supports the following RT codes:

0h - Fast Recovery

2h - Unspecified Delay

When either of these values is specified, the WM5102 will

resume toggling the CLK line within four cycles of the CLK line

frequency.

Segment Distribution

Note that any data channels that are assigned the same

SAMPLE_RATE_n or ASYNC_SAMPLE_RATE_n value must

also be assigned the same Segment Interval.
