In i.MX23 reference schematic revision C if fond a two design notes

 

I am using  SD / MMC Card Socket (4-Bit Databus)

 

Design Notes

 

1) The SD/MMC socket should an integrated, normally open mechanical Card Detect (I implement this note)

2) The i.MX23 has integrated pull up resistors for the SD/MMC DATA and CMD signals that must be enabled by setting a register (How can I do this?)
