10.2.3 Extended instructions (bit H = 1)

10.2.3.1

Screen_conf

Screen_conf:

• If bit L = 0, then the two halves of a split screen are connected in a standard way i.e.

column 1/81, 2/82 to 80/160.

• If bit L = 1, then the two halves of a split screen are connected in a mirrored way i.e.

column 1/160, 2/159 to 80/81. This allows single layer PCB or glass layout.

10.2.3.2

Disp_conf

Bit P: The P bit is used to ﬂip the display left to right by mirroring the column data, as

shown in Figure 18. This allows the display to be viewed from behind instead of front and

enhances the ﬂexibility in the assembly of equipment and avoids complicated data

manipulation within the controller.
