Partial Smooth Scroll
Partial smooth scroll displays one to three leftmost characters as fixed while the remaining ones undergo a
horizontal smooth scroll in the left and right direction. Specifically, the number of leftmost characters to be
fixed is specified by the partial scroll bits (PS1/0) in the scroll control register 2 (SCR2: R6). For example,
when bits PS1/0 are 10, the two leftmost characters are fixed; when 11, the three leftmost characters are
fixed.
Although half-size characters can be displayed in a fixed display area, they must be displayed in even-
numbered groups of two, four or six characters. Figure 31 shows an example of smooth scroll performed in
a display when bits PS1/0 are set to 10. The two leftmost characters (
remaining four characters undergo a smooth scroll.
