E22-900M22S Wiring (DIO1, DIO2, and BUSY)

Hello, I have put this as an issue in github before realising that there was a forum, apologies for the double posting. I am looking into the E22-900M22S chip. Can i use it with your library? Also, in your examples you use the E22-900T22S U chip which has the pins M0, M1 and AUX but the E22-900M22S has DI01 and DIO2 and BUSY. Can i assume that DIO1 is M0, DIO2 is M1 and BUSY is AUX? Also, I have been looking but i cant seem to find what are M0 and M1 and AUX are used for. Could you tell me what are they used for?
