Figure 2–8. Cursor-RAM Organization
2.7.2
The cursor-position (x,y) registers position the 64 x 64 cursor on the display screen. The cursor-position (x,y)
registers specify the location of the cursor bottom right corner on the display screen relative to the end of
the internal BLANK signal. Figure 2–9 shows the orientation of the x,y coordinates for positioning the cursor.
The values written to the cursor position registers represent the position of the bottom right corner of the
cursor. When zero is written to the cursor position x or cursor position y registers, the cursor is off the screen.
When the cursor position (x,y) is (1,1), only a single pixel of the cursor (cursor 63,63)is displayed and it
appears at the upper left corner of the screen.
