Note 1: UPS051 Horizontal blanking time (thblk) is adjustable by setting register HBLK; requirement of

minimum blanking time and minimum front porch time must be satisfied.

Note 2: UPS051 Vertical blanking time (tvblk) is adjustable by setting register VBLK. UPS051 accepts both

interlace and non-interlace vertical input timing.
