Device ID code：

ID code is defined by (A0&A1) pins. See multi-driver application in P10. Control signal input 8-bits

“111100A1,A0” (A1,A0)=00,01,10,11 then only matched driver will operate.

Register address：

Address of control register from $00H ~ $10H. The control signal here follow Device ID code

Data of register：

Definition of all control register see 6.3 EPD driver control register.
