Some host controllers have hardware limitations that prevent the use of some multi-block operations. Soft-Block reduces the implementation time for these controllers by converting multi-block transfers into a series of byte mode transfers. Implementation time, testing, and maintenance are reduced by relying on the common implementation of the translation code located in the bus driver.
During initialization of the host controller, the following options can be passed:
- SD_SLOT_USE_SOFT_BLOCK_CMD18
- SD_SLOT_USE_SOFT_BLOCK_CMD25
- SD_SLOT_USE_SOFT_BLOCK_CMD53_READ
- SD_SLOT_USE_SOFT_BLOCK_CMD53_WRITE
