Help 89c5131a with mmc card interface (SPI)!

Settled

can you please comment the code with what order you are sending that data? and what does it represents?

Solved

---------------------

I have few new questions

Before SD card goes into SPI mode
CMD0 is needed for it goes into SPI mode
After it went into SPI mode, CRC is ignored

So

1) As the CRC is ignored in SPI mode, do i still need to send 0x00 for the last byte of the command?

For example, if i want to send CMD55

I need to send ->(hex) 77 00 00 00 00 00? or just (hex) 77 00 00 00 00 & forget the last byte(CRC)

2) What are "STUFF bits" & "don't care" in the command format mean?
any example?
