General Data Format

This section describes the data format used by the three different data input sources (DRO, PWM, and

Waveform Memory). Four bits are used for storing the envelope value of snippets in Waveform Memory.

Interpretation of the data is different depending on ACCELERATION_EN. For an overview of the data

interpretation with and without Active Acceleration enabled, see Figure 31 and Figure 32.
