44-Pin Demo Board Lessons

Lesson 3: Rotate (Move the LED)
Building on Lessons 1 and 2, which showed how to light up a LED and then make it
blink with a delay loop, this lesson adds rotation. It will light up DS8 and then shift it to
DS7, then DS6 and on down to DS1, and then back to DS8.

Note:
Loads WREG with a literal value
Moves the contents of WREG to a file register
Moves the contents of a file register, either to WREG or back into
the file register (see note)
Rotate file register right
Rotate file register left
Moving a file register to itself looks like a NOP at first. However, it has a
useful side effect in that the Z flag is set to reflect the value. In other words,
MOVF fileregister,f is a convenient way to test whether or not the
value is zero without affecting the contents of the WREG.
