ON/OFF = “1”: Display ON
ALLON
Regardless of the data for display, all is on.
This control has priority over display normal/reverse commands.
ALLON = “0”: Normal display
ALLON = “1”: All display lighted
MON
Select Monochrome or Gradation display
MON = “0”: Gradation display mode
MON = “1”: Monochrome display mode
SHIFT
The shift direction of display scanning data in the common driver output is selected.
SHIFT = “0”: COM0ÆCOM127 shift-scan
SHIFT = “1”: COM127ÆCOM0 shift-scan
8.2.6 Display Control (2) Register
(At the time of reset: {REV,NLIN,SWAP,REF}=0H, read address: 9H)
Various control of display is set up.
REF
When MPU accesses to display RAM, the X address and data can reverse. The REF function shows in the table below:
The order of segment driver output can be reversed by register by register setting, lessening the limitation in placing IC when
assembling a LCD module.
* This specification is subject to be changed without notice.
