Display Attribute Designation
The HD66730/1 allocates 12 bits of the full-size 16-bit code character to an abbreviated character code and
2 bits to a display-attribute code (Figure 26). White/black inverted display, blinking display, and
white/black inverted blinking display can be designated for each full-size character (Table 21). Display
attribute control is performed for a 12
and a column of dots to the right and a row of dots to the bottom (Figure 27). The blinking cycle for
blinking display and white/black inverted blinking display is 64 frames. Blinking display is performed by
changing the display pattern every 32 frames. Since the 8-bit code designated for half-size characters
cannot accommodate a display attribute, they will always be displayed normally.
