Setting of CGROM and CGRAM character codes for up to 24 digits is now complete.
To further specify character codes continuously from DCRAM address 00H, dummy character
codes must be specified for DCRAM address 18H to 1FH (so that DCRAM address will be
incremented automatically and will be reset to 00H).
