of the 1st screen driving position register (R14h) and the start line (SS27-20) and end line (SE27-20) of
the 2nd screen driving position register (R15h) for the HD66766R. Note that incorrect display may
occur if the restrictions are not satisfied.

Notes: 1. When the total line count in screen division driving settings is less than the duty setting, non-selection
level driving is performed without the screen division driving setting range.
2. When the total line count in screen division driving settings is larger than the duty setting, the start line,
the duty-setting line and the lines between them are displayed and non-selection level driving is
performed for other lines.
