S6D0114 132-RGB X 176-DOT 1-CHIP DRIVER IC FOR 262,144-COLOR TFT-LCD DISPLAY
Preliminary

LG2–0:
Compare the data read from the GRAM by the microcomputer with the compare registers (CP17–0) by a
compare/logical operation and write the results to GRAM. For details, see the Logical/Compare Operation Function.
CP17–0:
Set the compare register for the compare operation with the data read from the GRAM or written by the
microcomputer.
Note: this function is not available when the external display interface (i.e. RGB interface or VSYNC interface) is in use.
Therefore, LG2-0 bits should be set to be “000”, respectively.

Note: 1) Data is written to GRAM in 18-bit units. Logical and compare operations are also performed in 18-bit units.
2) The write data mask(WM17-0) is set by the register in the RAM write data mask section
