Blink Function
Blinking Dot-Matrix Display Area:
The HD66410 can blink a specified area on the dot-matrix display.
Blinking is achieved by repeatedly turning on and off the specified area at a frequency of one sixty-fourth
the frame frequency. For example, when the frame frequency is 80 Hz, the area is turned on and off every
0.8 seconds.
The area to be blinked can be designated by specifying vertical and horizontal positions of the area. The
vertical position, or the rasters to be blinked, are specified by the blink start raster register (R8) and blink
end raster register (R9). The horizontal position, or the dots to be blinked in the specified rasters, are
specified by the blink registers (R6 and R7) in an 8-dot group; each data bit in the blink registers controls
its corresponding 8-dot group. The relationship between the registers and blink area is shown in Figure 15.
Setting the BLK bit to 1 in control register 2 after setting the above registers starts blinking the designated
area. Note that since the area to be blinked is designated absolutely with respect to the display RAM, it will
move along with a scrolling display (Figure 16).
