2.7. Display RAM Data and LCD
One bit of display RAM data corresponds to one
dot of LCD. Normal display and reverse display by
REV register are set up as follows.
• Normal display (REV = 0) :
RAM data = "0"; not lighted
RAM data = "1"; lighted
• Reverse display (REV = 1) :
RAM data = "0"; lighted
RAM data = "1"; not lighted
2.8. Segment Display Output Order/
Reverse Set Up
The order of display outputs, SEG0 to SEG127 can
be reversed by reversing access to display RAM
from MPU by using REF register, to lessen the
limitation on placing IC when composing an LCD
module.
