Purpose:
Defines a custom character.
Logic Controls Emulation Mode
The byte that follows the command byte contains an ASCII
character between X'20' and X'7F' of a keyboard key to be
redefined. This byte is followed by five bytes defining the bit
patterns of the user-defined character. Logic Controls Emulation
Mode allows only one keyboard key to be redefined. This means
that there is only one user-definable character in this mode. Once a
key is redefined, any occurrence of that character on the display
will change to the user-defined character. If a new key is redefined,
the previously redefined key is restored to the original character in
all places on the display and the newly redefined key is changed to
the user-definable character. Table A-1 on page A-3 shows the
format of these five bytes.
Note: A hyphen character in the table indicates a do-not-care bit.
The other values relate to the character pixel positions
shown in the diagram following the table. A value of 1 in the
data stream indicates that the related pixel position is ON; a
0 indicates that it is OFF.
