WM8786
Pre-Production
POWER-ON RESET
The WM8786 has an internal power-on reset circuit. The reset sequence is entered at power-on or
power-up (DVDD). Until the internal reset is removed, DOUT is forced to zero. DOUT remains zero
for a count equal to 32 sample clocks, after power up. (This count is driven by MCLK and is
independent of any external LRCLK).
