Hi Bin,
We can know the block transfer complete using IRQSTAT(Transfer Complete). But reading & writing in PIO mode takes time for byte by byte transfers and there is no way to poll that transfer, that's why I have added delay there.
Yes, I understand there is no such a register in Freescale eSDHC that provides status check for PIO mode. I am just wondering where the delay value 100 us comes from. Is it the required minimum value?
I can add comment like, * Wait before last byte transfer complete *\ Is that ok ??
Sure, adding a comment line would help a lot.
