9.6.3 Error Status Register (0x02)

The error bits are sticky and are not cleared by the hardware. This means that the software must clear the

Error Definitions:

•

MCLK Error : MCLK frequency is changing. The number of MCLKs per LRCLK is changing.

•

SCLK Error: The number of SCLKs per LRCLK is changing.

•

LRCLK Error: LRCLK frequency is changing.

•

Frame Slip: LRCLK phase is drifting with respect to internal Frame Sync.

9.6.4 System Control Register 1 (0x03)

The system control register 1 has several functions:

Bit D7:

If 0, the dc-blocking filter for each channel is disabled.

If 1, the dc-blocking filter (–3 dB cutoff <1 Hz) for each channel is enabled (default).

Bit D5:

If 0, use soft unmute on recovery from clock error. This is a slow recovery. Unmute takes the

same time as the volume ramp defined in register 0x0E.

If 1, use hard unmute on recovery from clock error (default). This is a fast recovery, a single step

volume ramp

Bits D1–D0: Select de-emphasis
