Enabled *
Disabled
Note:
Successfully entering the test-mode requires to set bit D6 of the sub address (test mode-bit)
to "1". In test-mode, the TUNER L&R inputs are reconfigured as output for the selected test
signals
This byte is used for testing and/or evaluation purposes only and must not be set to other
values than the default "11111110" in the application.
