The precautions regarding data storage that will be explained here are related to the initial setting of SGL.
By default, SGL already stores scroll data (including color data) for displaying numeric characters called ASCII cells in memory.
For this reason, if the ASCII scroll data stored in the default state is overwritten with other scroll data, the character numeric display functions supported by SGL cannot be used correctly.
ASCII scroll consists of 128 cells and 256 colors, and uses the normal scroll screen “NBG0”.
ASCII scroll data is stored in the RAM area as follows.
Character data: 2000H from address 0x25e60000 Map data: From 0x25e76000 to 1000H Pallet data: 20H from 0x25f00000
When using ASCII scroll, specify the offset when storing scroll data, and do not write the scroll data in the above area.
