7.4.5.2 Row Buffer Description
The start address for each buffer must be even.
Starting from address 2p+6, write a string corre-
sponding to the character codes and the possible
attributes as in the example below:
7.4.5.3 OSDRAM Mapping Example 1
The left column of Figure 53 gives an example of
OSDRAM mapping for the following configuration:
– The display uses basic parallel mode
– Only the two basic color palettes are used
– 36 characters are displayed per row
– The First Buffer Start Address (to be stored in
0002h and 0003h) is 0050h
– The Next Buffer Start Address to be stored in
buffer 1 (address 0050h and 0051h) is 409Eh
(009Eh is the address of buffer 2, and 40h is the
code for basic parallel mode. Refer to Section
7.4.7.1).
– The Next Buffer Start Address to be stored in
buffer 2 (address 009Eh and 009Fh) is 4050h
(0050h is the address of buffer 1, and 40h is the
code for basic parallel mode. Refer to Section
7.4.7.1 for more details).
7.4.5.4 OSDRAM Mapping Example 2
The right column of Figure 53 gives an example of
OSDRAM mapping for the following configuration:
– The display uses extended parallel mode
– The four color palettes are used
– 16 characters are displayed per row
– The First Buffer Start Address (to be stored in
0002h and 0003h) is 0090h
– The Next Buffer Start Address to be stored in
buffer 1 (address 0090h and 0091h) is 80C6h
(00C6h is the address of buffer 2, and 80h is the
code for extended parallel mode. Refer to Sec-
tion 7.4.7.1 for more details).
– The Next Buffer Start Address to be stored in
buffer 2 (address 00C6h and 00C7h) is 8090h
(0090h is the address of buffer 1, and 80h is the
code for extended parallel mode. Refer to Sec-
tion 7.4.7.1 for more details).
Note: To keep some OSDRAM locations free,
configure only those features that you really use
(color palettes, underline palettes), as shown in
the two examples.
