Page 20: In-System Tuning
Even if the device is integrated in the end application, it is still possible to make fine adjustments with the help of In-System Tuning. Like the In-System Debugging above, this is done by connecting I C signals from PPCMB to the TAS5782M device in the end-system. Figure 20. In-System Tuning Troubleshooting Power Cycle To perform a power cycle disconnect both the USB cable and the power supply from the board. -
