Data write
Single and multiple block write operations are supported in SPI mode.
Upon reception of a valid write command, the card sends a response token and waits for a
data block to be sent from the host. Write operations, as illustrated in
same rules as read operations (refer to
length and start address.
After receiving a data block, the card returns a data response token. If the data block
received contains no error, it is programmed. Throughout the programming operation the
card sends a continuous stream of busy tokens to the host (by holding the DataOut line
Low).
Erase & write protect management
The erase and write protect management procedures are the same in the SPI and SD
modes.
While the card is erasing or changing the write protection bits, it remains in the busy state
and holds the DataOut line Low.
