OSCILLATOR TRIM REGISTER (0x1B)
The TAS5711 PWM processor contains an internal oscillator to support autodetect of I2S clock rates. This
reduces system cost because an external reference is not required. Currently, TI recommends a reference
resistor value of 18.2 k
(1%). This should be connected between OSC_RES and DVSSO.
Writing 0x00 to register 0x1B enables the trim that was programmed at the factory.
Note that trim must always be run following reset of the device.

BKND_ERR REGISTER (0x1C)
When a back-end error signal is received from the internal power stage, the power stage is reset stopping all
PWM activity. Subsequently, the modulator waits approximately for the time listed in Table 19 before attempting
to re-start the power stage.
