TAILOR PIXELS TECHNOLOGY CO., LTD. FUNCTION Ground Supply voltage for logic Read/write selection input H : Read mode, L : Write mode Read/write enable signal. H: Read data/instruction H  L: Write data/instruction Register selection input H : Data signal, L : Instruction signal Reset signal. When RSTB=L, - ON / OFF register becomes set by 0. (display off) - Display start line register becomes set by 0 (Zaddress 0 set, display from line 0) After releasing reset, this condition can be changed only by instruction. Chip select signal, CS=L chip is active Back light anode
