Select bits C1 to C4 select Data latch 1 to Data latch 4 corresponding to COM 1 to COM 4
independently. If logic "1s" are selected to multiple select bits, the LCD display bits are written
to all corresponding data latches.
Example:
When logic "1s" are set to all select bits C1 to C4, and logic "0s" are set to all LCD display bits D1
to D50, logic "0s" are written to Data latch 1 to Data latch 4 by one data input. This leads to turning
off the entire LCD panel.

How to Decrease Transfer Time When Unused Segments Exist
The MSM9004-03/04 can operate even if segment data is not full. Input data as in the figure

Notes for Mounting the Surface Mount Type Package
The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which
are very susceptible to heat in reflow mounting and humidity absorbed in storage.
Therefore, before you perform reflow mounting, contact Oki’s responsible sales person for the
product name, package name, pin number, package code and desired mounting conditions
(reflow method, temperature and times).
