Hi, I am working on SBC2440I board. In that board K9S1208V0M-SSB0 nand flash is connected. referring to it's datasheet in program flow (writing page program) they have mentioned that after sending data we have to read status register and then check I/O6 = 1 or RnB = 1. I can understand why RnB= 1 condition is there. But can any one explain why I/O6 should be 1. why specifically I/O6 only? it is ultimately in out pin. datasheet link: www.datasheetcatalog.com/datasheets_pdf/K/9/S/1/K9S1208V0M-SSB0.shtml (page no. 11) Thanks, Tejas
