OSCILLATOR TRIM REGISTER (0x1B)
The TAS5705 PWM processor contains an internal oscillator for PLL reference. This reduces system cost
because an external reference is not required. Currently, TI recommends a trim resistor value of 18.2 k
(1%).
This should be connected between OSC_RES and DVSS.
The factory-trim procedure simply enables the factory trim that was previously done at the factory.
Note that trim always must be run following reset of the device.
Oscillator Trim Enable Procedure Example
Write data 0x00 to register 0x1B (enable factory trim).

BKND_ERR REGISTER (0x1C)
When a back-end error signal is received (BKND_ERR = LOW), all the output stages are reset by setting all
PWM and VALID signals LOW. Subsequently, the modulator waits approximately for the time listed in Table 23
before initiation of a reset.
