Address control (register AC) flags and some LCD to SRAM mapping (register LC) flags affect how data is
stored into the display buffer SRAM => Make proper adjustment to these two registers before writing data to
UC1602I display buffer SRAM.
These sequence can be performed in parallel 8-bit, I
2
C or S8 modes. These commands can be performed
under any operating mode (OM).
