Table 14 Register Map for Control Interface

Notes:

1.

All unused register bits should be set to zero

2.

The interface will initiate SWRB whenever R7 is addressed, regardless of the data input.

3.

SWRB is released on the next register write or after 4 MCLK cycles (which ever occurs first).

4.

Until the SWRB is released, DOUT is forced to zero.

5.

DOUT remains zero for a count of 32 sample clocks SWRB is released, this count is driven by MCLK and is

independent of any external LRCLK.
