VBLK start
VBLK start:
0 1 1 1 1 1 1 1 = 127 lines after start of vertical blanking interval
0 0 0 0 0 0 0 1= 1 line after start of vertical blanking interval
0 0 0 0 0 0 0 0 = same time as start of vertical blanking interval (default)
1 1 1 1 1 1 1 1 = 1 line before start of vertical blanking interval
1 0 0 0 0 0 0 0 = 128 lines before start of vertical blanking interval
Vertical blanking is adjustable with respect to the standard vertical blanking intervals as shown in Table 2–17. The
setting in this register determines the timing of the GPCL signal when it is configured to output vertical blank(see
register 03). The setting in this register is also used to determine the duration of the luma bypass function (see
register 07).
