Cylinder FG= 1 or 4, Ref time taken as Input time until PGMM time.
Timing calculation is performed based on the following.
Normal Head Ref time
10 u Head Ref time + 120 degree time 1H (=64us)
*120 degree time is defined as NTSC:11122us,PAL 13333us
Cylinder FG = 1 or 4 Base From Input time until PGMM time taken as
reference time. Timing calculation is performed as follow.
Normal head Ref time + 90 degree time
*90 degree time is defined as :NTSC : 8400us,PAL: 10000 us
