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 D49, 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. 11/15 ¡ Semiconductor MSM9004-01/02 How to Decrease Transfer Time When Unused Segments Exist The MSM9004-01/02 can operate even if segment data is not full.

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). 15/15
