3. Initialization

The LC78856M and LC78856V requires initialization when power is first applied and when settings are changed.

The LC78856M and LC78856V is initialized by setting the RSTB pin low. The length of the low-level period must

extend 1 µs beyond the point where the XIN input is applied. When RSTB is low, all digital filter and noise shaper

internal data is set to 0, and the D/A converter outputs an analog 0.
