7.25 8
×3 Output Mixer Registers (0xB0–0xB1)
TAS5518C
8-Channel Digital Audio PWM Processor
SLES238A – SEPTEMBER 2008 – REVISED JULY 2009

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. See TAS5518C Errata (SLEZ006).
Total data per register is 8 bytes. The default gain for each selected channel is 1 (0x0 80 00 00).
