Display Mode Register DMOD
Note: This register is not readable. Thus, do not use read-modify-write operations like
ANL, ORL to modify this register.
Display Feature Double Sizeand Double Width
Double Size and Double Width are selectable via serial attributes. The control codes are
‘0E’ for Double Width and ‘0F’ for Double Size. Now, there are 4 control codes available,
to modify the character size:
Since Double Width and Double Size control codes should not be interpreted by a pure
level 1 text-decoder, this size attributes have to be enabled by setting SFR-bit DSDW.
Double Width and Double Size characters are accomplished by skipping every second
character code after setting any of this following attributes where the remaining
displayable characters are stretched horizontally and thus conceating the character.
Although every second character is hidden, these codes will take effect if they are control
characters.
