When the CGRAM address is set, the cursor
will disappear on the display. When the
symbol register RAM is set, the cursor moves
to the corresponding symbol position, causing
this symbol to blink selectively.
When the cursor home command is executed
immediately after execution of this instruction
(before execution of RAM Address Set (1)),
the cursor will not be displayed. (Because
the address is set at address 30H of RE-1 of
the RAM map.)
