IBM Mode
IBM Mode allows nine user defined characters to be defined. See
Table A-2 for defined characters:
Table A-2. User character definition: IBM Mode
1. X'15' 6. X'1A'
2. X'16' 7. X'1C'
3. X'17' 8. X'1D'
4. X'18' 9. X'1E'
5. X'19'
The byte that follows the command byte represents an address
betweenX'15' and X'1A', or between X'1C' and X'1E' in the currently
selected character set. This byte is followed by eight bytes, which
define the actual bit patterns of the user-defined character.
Table A-3 on page A-4 shows the format of these eight 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
appropriate place in the data stream indicates that the
related pixel position is ON; a 0 indicates that it is OFF.
