1. PBLKTOG1 = 500
2. PBLKTOG2 = 785
3. PBLKTOG3 = 4095
4. PBLKTOG4 = 4095
5. THIS PBLK PULSE SEQUENCE IS USED IN THE EXAMPLE BELOW.
1. PBLKSTART = N – 2
2. PBLKSTOP = 001
3. THIS EXAMPLE SHOWS HOW PBLK IS LOW IN THE VERTICAL BLANKING REGION FROM PBLKTOG1 IN LINE PBLKSTART UNTIL PBLKTOG2 IN LINE PBLKSTOP.
AS SHOWN IN THE ABOVE FIGURE, PBLK REMAINS LOW FROM PBLKTOG1 TO PBLKTOG2.
