Windows shadow width
HW and VW bits in "Frame Control Register 5, 7, 9, 11" mean each horizontal and vertical width of window
shadow as shown in "Figure 15 : OSD window area". The actual value is calculated by (HW
×
2 Dots) and (VW
×
2 Lines). Shadow color is set by only black for the characteristics of shadowing. Also, it can display not only OSD
area (15 rows
×
30 columns) but also the extended area by window shadow. That is, to use window shadow
function, you may not construct the window less than the maximum OSD area.
Window Generation
As shown in "Figure III-6 : OSD window area", window size is determined by setting CSTR, RSTR, CEND, and
REND bits, which mean as a address with font unit in window area. The actual and physical start point of window
is the left-top point of the font area indicated 'Window Start Position' in "Figure 15 : OSD window area". Also, the
actual stop point of window is the right-bottom point of the font area indicated 'Window Stop Point'. If 'WEN' bit in
each window is enabled by setting to high, the window generated as above is displayed with the window priority
determined by 'WPR' bits in "Frame Control Register 13".
