• Description: 5-volt, 2-amp, 2.1-channel High-efficiency Digital Audio System Sound Terminal
• Manufacturer: STMicroelectronics

Register description
36/67
2.0 channels, two full-bridges (OCFG = 00)
Mapping:
Default modulation:
On channel 3 line out (LOC bits = 00) the same data as channel 1 processing is sent. On
channel 4 line out (LOC bits = 00) the same data as channel 2 processing is sent. In this
configuration, volume control or EQ have no effect on channels 3 and 4.
In this configuration the PWM slot phase is the following as shown in
Figure 14. 2.0 channels (OCFG = 00) PWM slots
