DEM 16215 SBH-PW-N Product specification 9. 9. INSTRUCTION INSTRUCTION DESCRIPTION DESCRIPTION (IE = "LOW" ) Outline To overcome the speed difference between the internal clock of KS0070B and the MPU clock, KS0070B performs internal operations by storing control information to IR or DR. The internal operation is determined according to the signal from MPU, composed of read/write and data bus (Refer to Table 5 ). Instruction can be divided largely into four kinds .

D : Display ON/OFF control bit When D = "1" , entire display is turned on . When D = "0" , display is turned off, but display data is remained in DDRAM . C : Cursor ON/OFF control bit When C = "1" , cursor is turned on.

Do not subject it to a mechanical shock by dropping it from a high place ,etc. If the display panel is damaged and the liquid crystal substance inside it leaks out , do not get any in your mouth . If the substance come into contact with your skin or clothes promptly wash it off using soap and water.
DEM 16215 SBH-PW-N Product specification 17. Others Liquid crystals solidify at low temperature (below the storage temperature range) leading to defective orientation of liquid crystal or the generation of air bubbles (black or white). Air bubbles may also be generated if the module is subjected to a strong shock at a low temperature.
