Note) In case of lower frequency, the deterioration of display quality, flicker etc., may be occurred.
7-2) Horizontal display position
①
In case ENAB is active
The horizontal display position is determined by ENAB signal. The input data corresponding to the 5
edge from rising of ENAB signal is displayed at the left end of the active area. (shown in Fig.3)

In case ENAB is “Low”
The display starts from the data of C108(clock) as shown in Fig.3.
Be careful that the module does not work when ENAB is Hi fixed.
7-3) Vertical display position
ENAB signal has no relation to the vertical display position.
