Register description
2.1 channels, two half-bridges + one full-bridge (OCFG = 01)
Mapping:
z FFX1A -> OUT1A
z FFX2A -> OUT1B
z FFX3A -> OUT2A
z FFX3B -> OUT2B
z FFX1A -> OUT3A
z FFX1B -> OUT3B
z FFX2A -> OUT4A
z FFX2B -> OUT4B
Modulation:
z FFX1A / 1B configured as binary
z FFX2A / 2B configured as binary
z FFX3A / 3B configured as binary
z FFX4A / 4B configured as binary
In this configuration, channel 3 has full control (volume, EQ, etc…). On OUT3 / OUT4
channels the channel 1 and channel 2 PWM are replicated.
In this configuration the PWM slot phase is the following as shown in Figure 16.
