Hello, I'm looking to understand the working of SD cards a little better. I noticed in Simon's code there are a few places where he is clocking the card with CS set high to initialize the card. I cannot find a place anywhere in the SD specifications document that says this is required for initialization. Is there someone who could tell me why we are doing this? Thanks
