up to 5 icons (SED1220/1221/1222) or 10 icons
(SED122A).
Following shows relationship between the static icons
functions, static icon RAM addresses and written data.
Electronic Volume RAM (register)
SED1220 contains the electronic volume function for
controlling the liquid crystal drive voltage V5 and density
of liquid crystal display. The electronic volume function
enables to select one of 32 voltage status of the liquid
crystal drive voltage V5 by writting 5-bit data to the
electronic volume RAM.
Following shows relationship between RAM addresses
set by the electronic volume and written data.
