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