Although there are 24 character display registers that can
be programmed for each row, not every programmed charac-
ter can be shown on the screen in 320–dot resolution. Usual-
ly only 24 characters can be shown in this resolution at most.
This is induced by the time that is required to retrace the H
scan line. At 480–dot resolution, a total of 24 characters can
be displayed on the screen if the horizontal delay register is
set properly.
Figure 13 illustrates the timing of all output signals as a
function of window and fast–blanking features. Line 3 of all
three characters is used to illustrate the timing signals. The
shaded area depicts the window area. The characters on the
left and right appear identical except for the FBKGC bit. The
middle character does not have a window as its background.
Notice that signal HTONE/PWMCK is active only in the win-
dow area. Timing of the signal FBKG depends on the config-
uration of the FBKGC bit. The configuration of the FBKGC bit
affects only the FBKG signal timing; it has no effect on the
timing of HTONE/PWMCK. Waveform ‘R, G, or B’, which is
the actual waveform at R, G, or B pin, is the logical OR of
waveform ‘character R, G, or B’ and waveform ‘window R, G,
or B’. ‘Character R, G, or B’ and ‘window R, G, or B’ are inter-
nal signals for illustration purpose only. Also notice that
HTONE/PWMCK has exactly the same waveform as ‘win-
dow R, G, or B’.
