LCD DRIVER CIRCUIT
LCD Driver circuit has 34 commons and 80 segments signals for driving LCD. Data from ICONRAM / CGRAM /
CGROM are transferred to 80-bit segment register serially, and then they are stored to 80-bit shift latch. In case of
2-line display mode COM1 - COM16, COMI1 and COMI2 have 1/18 duty, in 3-line mode COM1 - COM24, COMI1
and COMI2 have 1/26 duty, and in 4-line mode COM1 - COM32, COMI1 and COMI2 have 1/34 duty ratio. SEG bi-
directional function is selected by DIRS input pin, and COM shift direction is selected by function set instruction
"SS" bit.
