Can you tell me the meaning of the abbreviation in this PlayStation controller ? Answered

My friend gave me this controller I'm trying to fix it but I don't know the meaning of these abbreviations, all i know is ACK = Acknowledge CLK = Clock and the Positive and Ground connection. I already searched for the color coding of the wires and try to guest it but still no luck. In case of you cant see the image clearly here are the abbreviations DO,OI,CLK,ACK,CS,Gnd,+3.7 and VDD or VDC im not sure about the VDD or VDC.

DO= data out

DI= data Input



CS=chip select


red wire must be 3.3V not 3.7

yellow might be VDD=Vdd (drain) Vcc and Vdd usually mean the same thing
