SPI Interface Layer for SDIO Card

Started by maneeshjain1981 December 1, 2007
I am using the LPC2138 as SPI Host controller & CSR Unifi Chip as SDIO
card(in SPI Mode).

I need to connect the Unifi Chip(SPI Mode) with the LPC.

I am able to initiliaze the Unifi Chip in SPI Mode using CMD0.
The CMD5 & CMD52 is also working fine,

I am facing a problem to implement the CMD53.

Can you someone please help me out to implement the CMD53 in SPI mode.

If somebody had a soucre code for CMD53 for SPI host controller, Please
send to me.
