Decay time is limited based on NADC ratio that is selected. For
NADC = 1, Max Decay time = 4 seconds
NADC = 1.5, Max Decay time = 5.6 seconds
NADC = 2, Max Decay time = 8 seconds
NADC = 2.5, Max Decay time = 9.6 seconds
NADC = 3 or 3.5, Max Decay time = 11.2 seconds
NADC = 4 or 4.5, Max Decay time = 16 seconds
NADC = 5, Max Decay time = 19.2 seconds
NADC = 5.5 or 6, Max Decay time = 22.4 seconds
