O0 ~ O79 O LCD driving segment (column) output. 80
The output level varies by the trailing edge of the LP.
D0 ~ D3 I Display data input 4
XSCL I Shift clock input of display data (trailing edge trigger) 1
LP I Latch pulse input of display data (trailing edge trigger) 1
EIO1, EIO2 I/O Inable input and output. 2
Set to input or output depending on the SHL input level.
The output is reset by the LP input and, after receiving 80 bit
data, it automatically rises to HIGH.
SHL I Shifting direction choice and input/output controlling input to the 1
EIO terminal.
When data are input to (D3, D2 ...D0) terminals in the order of
(a,b,c,d,e,f,g,h).....(w,x,y,z), relations between data and segment
outputs are as follows:
(Note) Relations between data and segment outputs are
determined independent from the shift clock number.
FR I Input of the alternating signal of the LCD drive output. 1
