• DAP channel 6 is mapped though the 8×2 crossbar mixer (0xAF) to PWM channel 6

Note that the pass-through output mixer configuration (0xD0 bit 30 = 1) is recommended. Using the

remapped output mixer configuration (0xD0 bit 30 = 0) increases the complexity of using some features

such as volume and mute.

Total data per register is 8 bytes. The default gain for each selected channel is 1 (00 80 00 00) and 0.5

value is (00 40 00 00) value. The format is 5.23
