Address data is specified in P[5:0]

The address range can be set as 000000~100010

When the specified address is out of range, the address will be set to “000000”.

The Reset initialize condition of the DDRAM address is “000000”

Command Register Addresses(read mode):

P[5:0]=23h-----REG1

Register address for software reset condition and EVR setting

It is able to control 32-step electrical register (EVR).

It is able to set V0 voltage level (the max level voltage of LCD driving voltage).

Electrical volume resister (EVR) is set “00000” in reset initialize condition

In “00000” condition, V0 voltage output VLCD voltage.

It is prohibited to set EVR V0 voltage under 2.5V.
