DocID15251 Rev 8
2.1 channels, two fullbridge + 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 ternary
FFX2A/2B configured as ternary
FFX3A/3B configured as ternary
FFX4A/4B is not used
In this configuration, channel 3 has full control (volume, EQ, etc…). On OUT4 channel the
