GRAPHICS OPERATION FUNCTION
The S6D0114 can greatly reduce the load of the microcomputer graphics software processing through the 16-bit bus
architecture and internal graphics-bit operation function. This function supports the following:
1. A write data mask function that selectively rewrites some of the bits in the 18-bit write data.
2. A logical operation write function that writes the data sent from the microcomputer and the original
RAM data by a logical operation.
3. A conditional write function that compares the original RAM data or write data and the compare-bit data and
writes the data sent from the microcomputer only when the conditions match.
Even if the display size is large, the display data in the graphics RAM (GRAM) can be quickly rewritten.
The graphics bit operation can be controlled by combining the entry mode register, the bit set value of the RAM-
write-data mask register, and the read/write from the microcomputer.
