Input/output pins for chip selection

When L/R register is ‘0’, EIO1 is set output, and EIO2 is set for input.

EIO1 : segment chip enable output, as default segment is enabled internally and be non-selected

after 16,32,48,64 or 80 bits of data have been read. Depend on select mode.

ElO2 :common shift data input, no sift data output

When L/R register is ‘1’, EIO1 is set for input, and EIO2 is set for output.

EIO1, EIO2 EIO1 :common shift data, no shift data output

ElO2 : segment chip enable output, as default segment is enabled internally and be non-selected

after 16,32,48,64 or 80 bits of data have been read. Depend on select mode.

During output, set to "H" while LP • XCK is "H" and after 96 bits of data have been read, set

to "L” for one cycle (from falling edge to failing edge of XCK), after which it returns to "H".

During input, the chip is selected while El is set to "L" after the LP signal is input. The chip is

non-selected after 96 bits of data have been read.

LCD drive output pins

CS0 ~CS95

Corresponding directly to each bit of the data latch, one level (V0, V2, V3, VSS) is selected and

output.

Table of truth values is shown in "TRUTH TABLE" in Functional Operations.

CAP1- DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2- terminal.

CAP1+ DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1- terminal.

CAP2- DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2- terminal.

CAP2+ DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2- terminal.

CAP3+ DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1- terminal.

CAP4+ DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2- terminal.

VOUT

XCS

DC/DC voltage converter. Connect a capacitor between this terminal and VSS.

This is the command mode select pin. When XCS=”L” then write command to the LCD, when not

used the command mode then must fixed to VDD . See Figure1

SID

The command data. See Figure1

SCLK The serial clock input. See Figure1
