2.6 PWM Timing, Interchannel Delay Registers

For maximum performance, the PWM timing must be optimized for the specific configuration and PCB layout. The default values in TAS5066 is properly not optimal in many designs and therefore the interchannel delays must be pro- grammed by I2C to the TAS5066 at startup and after every system reset.
