FUNCTIONAL DESCRIPTION

Pin Functional Description

• IO1, IO80, SHL

IO1 and IO80 are I/O pins of the 80-bit bi-directional shift register. The shift direction can be

selected by the SHL pin. Set the SHL pin to "H" or "L" level during power-on. Table 1 gives

functions of IO1, IO80, and SHL.

Input

The scanning data from the LCD controller LSI is input into

IO1 synchronized with the clock pulse.

*1

Shift register contents output pin. The scanning data which

output was input into IO1 is output from IO80 with 80-bit delay,

synchronized with the clock pulse.
