P112 Min DATEM 
 
 
This parameter determines whether the Min DATEM is in use or not.  
Options are: 
0 = No (Min DATEM not in use) DATEM update will not be restricted and will 
update right back to the ringdown. 
1 = Yes (Min DATEM applied) DATEM update is restricted to the values entered 
in P109, P110 and P111, which will ensure that DATEM is held off the 
ringdown.
