various control setting of display
a) REF command
When CPU tries to access display RAM, the relation between X address and write data is changed by
command, normal or headfirst.
The output sequence of display data to segment driver can be controlled by register setting. The IC can
be placed in panel with less constraint at application.
b) SWAP command
When CPU tries to access display RAM, the display data can be swapped.
SWAP=”0”: Normal state, D

SWAP=”1”: SWAP mode on : The swapped data of D

c) NLIN command
n line inversion ON/OFF control.
NLIN=”0”: n line inversion OFF. Polarity signal, FR is inverted every other frame.
NLIN=”1”: n line inversion ON. The n lines are inverted according to the contents of n line inversion
register
d) REV command
The relation between RAM data and display data is defined by this command.
REV=”0”: The display data are reflected the RAM data until that time.
REV=”1”: The display data are reflected the opposite data from RAM data.
