Vertical blanking start
Vertical blanking (VBLK) start
0111 1111 = 127 lines after start of vertical blanking interval
0000 0001 = 1 line after start of vertical blanking interval
0000 0000 = Same time as start of vertical blanking interval (default) (see Figure 3-5)
1111 1111 = 1 line before start of vertical blanking interval
1000 0000 = 128 lines before start of vertical blanking interval
Vertical blanking is adjustable with respect to the standard vertical blanking intervals. The setting in this
register determines the timing of the GPCL/VBLK signal when it is configured to output vertical blank (see
register 03h). The setting in this register also determines the duration of the luminance bypass function
(see register 07h).
