INSTRUCTION SET
8.3.3. CSRFORM
Sets the cursor size and shape. Although the cursor is
normally only used in text displays, it may also be used in
graphics displays when displaying special characters.
8.3.3.1. CRX
Sets the horizontal size of the cursor from the character
origin. CRX is equal to the cursor size less one. CRX must
be less than or equal to FX.
Table 14. Horizontal cursor size selection
8.3.3.2. CRY
Sets the location of an underscored cursor in lines, from
the character origin. When using a block cursor, CRY sets
the vertical size of the cursor from the character origin.
CRY is equal to the number of lines less one.

8.3.3.3. CM
Sets the cursor shape. Always set CM to 1 when in
graphics mode.
CM = 0: Underscore cursor
CM = 1: Block cursor
8.3.4. CSRDIR
Sets the direction of automatic cursor increment. The
cursor can move left or right one character, or up or down
by the number of bytes specified by the address pitch, AP.
When reading from and writing to display memory, this
automatic cursor increment controls the display memory
address increment on each read or write.
