2.1 channels, two full-bridges + one external full-bridge (OCFG = 10)
Mapping:
z FFX1A -> OUT1A
z FFX1B -> OUT1B
z FFX2A -> OUT2A
z FFX2B -> OUT2B
z FFX3A -> OUT3A
z FFX3B -> OUT3B
z EAPD -> OUT4A
z TWARN -> OUT4B
Default modulation:
z FFX1A/1B configured as ternary
z FFX2A/2B configured as ternary
z FFX3A/3B configured as ternary
z FFX4A/4B is not used
In this configuration, channel 3 has full control (volume, EQ, etc…). On OUT4 channel the
external bridge control signals are muxed.
In this configuration the PWM slot phase is the following as shown in Figure 16.
