Notes: 1. When the SFT pin is grounded, the SEG1 pin output is connected to the far left of the LCD
panel, and when the SFT pin is high, the SEG60 pin output is connected to the far left.
2. SEG1 to SEG20 data is identical to SEG21 to SEG40 and SEG41 to SEG60 data.
3. The lower five bits (D4 to D0) of SEGRAM data determine on or off display of each segment. A
segment is selected (turned on) when the corresponding data is 1, and is deselected (turned
off) when the corresponding data is 0. The upper three bits (D7 to D5) are invalid.
