HORIZONTAL DISPLAY POSITION

The horizontal display position is determined by ENAB signal and the input data corresponding to the rising edge ENAB

signal is displayed at the left end of the active area.

Notes:

1.

When ENAB is fixed at "Low", the display starts from the data of C104 (clock) as shown in Fig. 2-1~3. Be careful the module does not work when ENAB is fixed "High".
