Notes: 1. Always specify GHP and GVP, in that order, at the end of each line.
2. Set GINT to 1 in the GVP setting to generate an OSD graphics interrupt.
3. Set GLAST to 1 in the GVP setting for the last line in the graphics display. Also, set the GVP value to a smaller
value than the position of the current line. (In the example in table 7-5, GVP = x'20' is smaller than GVP = v'58'.)
