SET CHARACTER CODE
Writes the character code given by C
7–C0 into the
character data RAM at the location pointed to by the
contents of the cursor address register. The contents of
the cursor address register are then modified as specified
by the last SET CURSOR DIRECTION instruction.
SET CGRAM ADDRESS
Presets the contents of the CGRAM address register to
the position of one of the four user definable characters.
The address is specified by A
1 and A0.
SET CGRAM DATA
Loads the bit pattern D
4–D0 into the CGRAM location
specified by the current contents of the CGRAM address
register. The contents of the CGRAM Address Register
are incremented following each write of a SET CGRAM
DATA instruction by the CPU.
See section 4.3, Loading CGRAM.
