condition of Key scan signal output. The terminal, which is set to "L", does not output Key scan signal as
shown in following table.
5 terminals numbered from 44 to 45 as shown in following table.
Duty select instruction is which sets LCD driving duty ratio 1/3 or 1/4 duty.
No.43 terminal is change Common terminal or segment terminal shown below.
Table 1
E.V.R. resister set instruction adjusts the contrast of the LCD, and selects.
One LCD driving voltage VLCD out of 8 voltage-stages by setting E.V.R. register.
Set the binary code “000” when contrast adjustment is unused.
Power save mode reduces the operating current of application using Display Off and selects a terminal
This instruction assigns a function of output terminal either segment output or Key scan signal output to
