I'm trying to include an SD card slot in one of my designs. The whole SD format seems confused at best, and I can't seem to find a definitive answer to what I need to wire up.
In hardware, I'm planning on using a socket from Yamaichi Electronics , FPS009-3202-BL, along with a TXB0104 level shifter to handle 5 V to 3.3 V signal conversion. The microcontroller is an ATtiny4313, which has MOSI on pin 17, MISO on pin 18, and SCK on pin 19. I'm not sure what to do with SS or even if I've wired it correctly. Here's a screenshot of what I have so far:
How can I proceed from here?
