Various display controls are set up.
When the MPU accesses the display RAM, the X address and data can reverse. The REF
function is shown in the table below:
Note: maxH: The maximum X-address in each access mode.
The order of segment driver output can be reversed by the register, by register setting, thus
lessening the limitations in placing the IC during an LCD module assembly.

The NLIN control n-line alternate driver.
NLIN = “0”: n-line alternate driver OFF. In each frame, the alternate signals (M)
NLIN =”1”: n-line alternate driver ON. Alternate is performed in accordance to
When data are written to the display RAM, the bit order of the written data are
SWAP = “0”: Normal mode
SWAP = “1”: In data writing, bit order is exchange.
