GH/GL command (GH3 to GH0, GL3 to GL0)
These bits set the output levels of the high-frequency group and low-frequency group outputs, respectively. The
input code and the corresponding output level are shown in table 4. Note that the 0dB point is typically 93% of
the supply voltage. Any value above 0dB results in amplitude clipping of the output waveform.
