OSD PRESSOR FOR MONITOR (PRELIMINARY)

(ii) If CH[5:0] is greater than 46 and less than or equal to 60 (46 < CH[5:0]
≤
60), all lines are
repeated tow or three times. The lines that are repeated three times are chosen by the following formula.
where N = 1, 2, 3, ... and M = round { 14 / ( CH[5:0] - 46 ) }.
(iii) If CH[5:0] is greater than 60 and less than or equal to 64 (60 < CH[5:0]
≤
64), all lines are repeated three or
four times. The lines that are repeated four times are chosen by the following formula.
where N = 1, 2, 3, ... and M = round { 14 / ( CH[5:0] - 60 ) }.
CH's reference value is 18, and even if you input 0, it operates in the same way as when CH=18. The repeating
line-number is limited to 16. If the M value is less than or equal to 1, all lines of the standard font are repeated
more than once.
Auto Height Control
function is executed by enabling 'AutoH' bit in "Frame Control Register 0" and setting the
number of OSD fonts that you need vertically at 'AREF' bits in "Frame Control Register 4".
At this time, the reason of that 'AREF' are 6 bits is as follows : At first, we suppose that the maximum of vertical
resolution is 1200 lines on Monitor. In case that the minimum of font height is 18 lines, the number of OSD font is
vertically 67 (=1200/ 18). Therefore, it is satisfied that 'Auto Height Control Reference Number' is 63 (=2
6
).
That is, if you enable 'AutoH' bit and set 20 to 'AREF' bits, height lines in a font is determined to display 20 fonts
vertically at maximum resolution as shown in the figure below, and the same size of OSD display regardless of
changing resolution. If the font height calculated by AREF value is less than 18 lines, the font height displayes as
many as 18 lines.
