Inter-digit time for pulse format: 
The inter-digit time is the value programmed on this location, divided by 
the pulse-rate (PPS) of the programmed format. This is programmed in a 
binary way: in order to program the value “10”, options 2 and 4 must be 
selected, for value “5”, options 1 and 3 must be selected. 
Ex: when the value 10 is programmed on segment 4 and a pulse format 
of 20 PPS is used, the inter-digit time is 10/20 = 0.5 sec.
