SPI Interface Layer for SDIO Card
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.
