FD1000A
z 1/4 Duty , SCK is stopped at low level
3/4COM LCD Driver
z 1/4 Duty , SCK is stopped at high level
Control Data Functions
z Display Data : D1 to D156 (1/3 Duty), D1 to D204 (1/4 Duty)
When the bit of a display data is “1”, the LCD display is turn ON
When the bit value is “0”, the display is turn OFF.
z Duty Selection : Duty select address is which sets LCD driving duty ratio 1/3 or 1/4 duty.
Address = 41 Hex, 1/3 Duty ( 3-Common 52-Segment LCD Driver )
Address = 80 Hex, 1/4 Duty ( 4-Common 51-Segment LCD Driver )
z DR : 1/2 or 1/3 Bias Selection Bit
DR data = “0” , 1/2 Bias Drive
= “1” , 1/3 Bias Drive
z SC : Segment ON/OFF Control Bit
SC data = “0” , Display ON
= “1” , Display OFF
z BU : Power saving Control Bit
BU data = “0” , Normal Mode
= “1” , Power-saving Mode.
In this mode the Oscillator is stopped and the segment pins output Vss levels.
z CU : LCD dividing resistors selection bit (Only 1/4 Duty Mode)
CU data = “0” , Normal Mode (RLCD=R)
= “1” , Low current Mode (RLCD=2*R)
