7. CONTROL DATA
Using the serial data, following functions can be utilized as follows.
Serial communication timing and waveform
(1) The set of display mode
(2) The display-position adjustment(Horizontal) : Table 2.
(3) The display-position adjustment(Vertical)
(4) CLK•DELAY
(5) Under-scan mode
(6) Masking mode
After serial data are transferred into the module, it is latched by CNTSTB. The above functions are effective
after the data is latched.
Please keep CNTSTB to be "L" during transferring data. The serial data can be changed at any time, however,
the display may be interrupted. We recommend that the backlight is turned-off by RBTC signal during
changing the serial data.
CNTSEL = “L”
CNTSEL = “H” or “Open” : Internal fixed value (default) is effective
