132 SEG / 65 COM DRIVER & CONTROLLER FOR STN LCD
ADC Select (Segment Driver Direction Select)
Reverse Display ON / OFF
Entire Display ON / OFF
Select LCD Bias

Changes the relationship between RAM column address and segment driver. The direction of segment driver
output pins can be reversed by software. This makes IC layout flexible in LCD module assembly.
ADC = 0: normal direction (SEG0
ADC = 1: reverse direction (SEG131
Reverses the display status on LCD panel without rewriting the contents of the display data RAM.
Forces the whole LCD points to be turned on regardless of the contents of the display data RAM. At this time,
the contents of the display data RAM are held. This instruction has priority over the reverse display ON / OFF
instruction.
EON = 0: normal display
EON = 1: entire display ON
Selects LCD bias ratio of the voltage required for driving the LCD.
