Evaluation Character Fonts
The character font for evaluation of the LM1276 is shown in
the 8 available ROM banks. Each bank is shown with in-
creasing character address going from upper left to lower
right. The actual font will depend on customer customization
requirements.
Note that the first two character codes of the two-color font in
ROM bank 4 (0x00 and 0x01) are carried over from the
LM1237 ROM where they were reserved for the End-Of-
Screen (EOS) and End-Of-Line (EOL) codes respectively.
In the case of the LM1276, these two locations can be used
for displayable characters as long as they are not needed
when this bank is addressed from Bank Select Register 0. If
it is addressed from Bank Select Registers 1, 2 or 3, then
these two lower characters will be usable. Please see the
section “END-OF-LINE and END-OF-SCREEN CODES”.
Similarly, the first two characters in any bank, which is ad-
dressed from Bank Select Register 0 will not be usable since
those addresses will be interpreted as the EOL and EOS
codes.
