#103661 - datasheet
Responding to: ???'s previous message
I was looking at that document and thats where I got the info
on the CID from. Do all SPI devices use this timing? I'm looking at page 99 on that datasheet at the timings used, figure
5-11; If the commands are a single byte, and they are followed by 5 more bytes, what is contained in these 5 bytes? Parameters for the command byte? Take into consideration the reset command, there are no params, so could the remaining bytes just be low? Does that mean I still have to generate 44 clocks (40 for the bytes, plus 4 clocks, according to this figure) before the response begins to come in?

God I'm going to have to learn to use the 8051 stack, something I've been dreading :)
