Production Data

MASTER POWERDOWN
This control bit powers down the references for the whole chip. Therefore for complete powerdown,
all DACs should be powered down first before setting this bit.
MASTER MODE SELECT
Control bit MS selects between audio interface Master and Slave Modes. In Master mode LRCLK
and BCLK are outputs and are generated by the WM8766. In Slave mode LRCLK and BCLK are
inputs to WM8766.
MASTER MODE LRCLK FREQUENCY SELECT
In Master mode the WM8766 generates LRCLK and BCLK. These clocks are derived from the
master clock and the ratio of MCLK to LRCLK is set by RATE.
