Cursor Control
The cursor control (Figure 9) includes the B/W, C, and B bits.
B/W: When B/W is 1, the character at the cursor position is cyclically (every 32 frames) displayed with
black-white inversion.
C: The cursor is displayed on the 8th raster-row when C is 1. The cursor is displayed using 5 dots in the
8th raster-row for 5
B: The character indicated by the cursor blinks when B is 1. The blinking is displayed as switching
between all black dots and displayed characters every 32 frames. The cursor and blinking can be set to
display simultaneously. When LC and B = 1, the blinking is displayed as switching between all white
dots and displayed characters.
