EGISTERS
UC1682 contains registers which control the chip operation. These registers can be modified by commands.
The following table is a summary of the control registers, their meanings and their default values.
Commands supported by UC1682 will be described in the next two sections. First, a summary table,
followed by a detailed instruction-by-instruction description.
Name:
The Symbolic reference of the register.
Note that, some symbol name refers to bits (flags) within another register.
Default:
Numbers shown in
Bold
font are default values after
Power-Up-Reset
and
System-Reset
.

Description
SL
7
0H
Scroll Line. Scroll the displayed image up by SL rows. The valid SL value is
between 0 (for no scrolling) and (79– 2xFL). Setting SL outside of this range
causes undefined effect on the displayed image.
FL
4
0H
Fixed Lines. The first FLx2 lines of each frame are fixed and are not
affected by scrolling (SL). When FL is non-zero, the screen is effectively
separated into two regions: one scrollable, one non-scrollable.
When partial display mode is activated, the display of these 2xFL lines is
also controlled by LC[0].
CR
