Peak value of uplink audio signal during last frame in dB decimal point and
sign is not shown, ie. -10.5 is show 105.
bbb
Moving average of peak levels, decimal point and sign is not
is show 105.
ccc
Cut off counter value of last frame. This counter counts how many samples are
saturated during last frame.
ddd
Moving average of cut off counter
The display is reset and restarted when call is taken (if FT display counters are enabled).
When call is terminated the display is froz en to show last values. Display values will not
be saved to the EEPROM.
