Output select normal, right and left (bits OSN, OSR and OSL)
Note
1.
Power-on reset state.
In case the dub-mix mode is selected via the input select function, the performance of mix-left, mix-right and mix-stereo
modes is changed to support audio dubbing input mixing. The hi-fi channel is available for the input select function and
normal sound is available at the output for monitoring the linear audio recording. The auto-normal state is ignored during
the dub-mix mode and the hi-fi playback signal is muted instead.

NVELOPE OUTPUT SELECT
The output signal on pin ENVOUT is selected via the envelope select function.
In the playback mode the HF envelope displays the amplitude of the left channel carrier. Display of the right channel
carrier amplitude for special measurement purposes can be selected via test 10 in the test mode.
