STA339BW

2.0 channels, two full bridges (OCFG = 00)

 FFX1A -> OUT1A

 FFX1B -> OUT1B

 FFX2A -> OUT2A

 FFX2B -> OUT2B

 FFX3A -> OUT3A

 FFX3B -> OUT3B

 FFX4A -> OUT4A

 FFX4B -> OUT4B

 FFX1A/1B configured as ternary

 FFX2A/2B configured as ternary

 FFX3A/3B configured as lineout ternary

 FFX4A/4B configured as lineout ternary

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 17.
