Number of words to transfer, as referenced in WORD_LENGTH in HW_SSP_CTRL1. The run bit and DMA
request will clear after this many words have been transferred. In SD/MMC, this should be a multiple of the
block size.
Reserved
SD/MMC block count. This value one less than the number of blocks to transfer. For example setting a value
of one will transfer two blocks. This must satisfy equation HW_SSP_XFER_SIZE_XFER_COUNT = (1
shiftleft BLOCK_SIZE) x (BLOCK_COUNT+1) for BLOCK_COUNT greater than zero. This is also SPI/SSI
control word[15:8] for RX transfers.
SD/MMC block size encode. When BLOCK_COUNT is nonzero, the actual block size is (1 shiftleft
BLOCK_SIZE). For example setting a value of 9 will result in a block size of 512 bytes. When BLOCK_COUNT
is zero, BLOCK_SIZE is ignored and HW_SSP_XFER_SIZE_XFER_COUNT represents the single block
size or the number of byte to transfer. This must satisfy equation HW_SSP_XFER_SIZE_XFER_COUNT =
(1 shiftleft BLOCK_SIZE) x (BLOCK_COUNT+1) for BLOCK_COUNT greater than zero.
