Window top border position =
TH ✕ (BC17 ✕ 16² + n)
(n: setting value, TH: HSYNC cycle,
BC17: bit 7 of block control register 1)
Notes 1: Set values except “0016” to WN1 when BC17 is “0.”
2: Set values fit for the following condition: WN1 < WN2.
3: When OC21 of OSD control register 2 is “0”, TH is 1 HSYNC.
And when “1”, TH is 2 HSYNC.
