The display is to be used by special debugging DSP SW which can put some useful
information to the memory locations on API RAM. When this display is selected then
MCU copies the contents of those memory locations into display with format specified
above.
This display may not be included in normal SW releases.

Control word for DSP Audio Enhancements in decimal format.
The control word is sent to the DSP in the MDI_AUDIO_CONFIGURE message.
Prior using this display the control word must be written to location 31/32 of the
SIM in decimal format.
When the display 71/72 is choosen from the menu, (EXECUTE MODE) the control word is
sent to the DSP in MDI_AUDIO_CONFIGURE message immediately. MDI_AUDIO_CONFIGURE
message is also sent every time when this display is entered using arrow keys and
previous display was 72/71.
Used together with display 72/71, this display makes rapid on/off switching of audio
DSP algorithms possible. Switching with arrow keys is possible only after this
display or display 72/71 has been selected from the menu. This prevents accidental
on/off switching of algorithms when browsing displays by arrow keys.
Entered values are not saved to EEPROM, so it is possible to reset to the correct
values by removing the battery.
