2.4.8 Pulse Width Modulation Schemes
TAS5548 supports three PWM modulations schemes: AD Mode, BD Mode and Ternary Mode. Ternary
mode is selected using register 0X25, bit D5. For AD and BD Modulation schemes, this bit should be set
to 0. AD/BD mode is selected via input mux registers 0X30-0X33. Following PWM timing diagram shows
the three different schemes.
