LCD DRIVER CIRCUIT
LCD Driver circuit has 16 common and 80 segment signals for driving LCD. Data from CGRAM / CGROM are
transferred to 80-bit segment register serially, and then they are stored to 80-bit shift latch. COM1 to COM16 have
1/16 duty ratio. SEG bi-directional function is selected by DIRS input, and COM shift direction is selected by DIRC
input.
