2.1 channels, two full-bridges + one external full-bridge (OCFG = 10)
FFX1A -> OUT1A
FFX1B -> OUT1B
FFX2A -> OUT2A
FFX2B -> OUT2B
FFX3A -> OUT3A
FFX3B -> OUT3B
EAPD -> OUT4A
TWARN -> OUT4B
FFX1A/1B configured as C1B0 (default: ternary)
FFX2A/2B configured as C2B0 (default: ternary)
FFX3A/3B configured as C3B0 (default: ternary)
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 38.
