[14:12] Host DMA Buffer Boundary
The large contiguous memory space may not be available in the virtual
memory system. To perform long SDMA transfer, System Address register
is updated at every system memory boundary during SDMA transfer.
These bits specify the size of contiguous buffer in the system memory. The
SDMA transfer waits at the every boundary specified by these fields and
the Host Controller generates the DMA Interrupt to request the Host Driver
to update the SDMA System Address register. At the end of transfer, the
Host Controller issue or not issue DMA Interrupt. In particular, DMA
Interrupt is not issued after Transfer Complete Interrupt is issued.
If this register is set to 0 (buffer size = 4K bytes), lower 12-bit of byte
address points data in the contiguous buffer and the upper 20-bit points the
location of the buffer in the system memory. The DMA transfer stops if the
Host Controller detects carry out of the address from bit 11 to 12.
These bits are supported if the SDMA Support in the Capabilities register is
set to 1 and this function is active if DMA Enable in the Transfer Mode
register is set to 1.
000b = 4K bytes (Detects A11 carry out)
001b = 8K bytes (Detects A12 carry out)
010b = 16K Bytes (Detects A13 carry out)
011b = 32K Bytes (Detects A14 carry out)
100b = 64K bytes (Detects A15 carry out)
101b = 128K Bytes (Detects A16 carry out)
110b = 256K Bytes (Detects A17 carry out)
111b = 512K Bytes (Detects A18 carry out)

BLKSIZE
[11:0] Transfer Block Size
This register specifies the block size of data transfers for CMD17, CMD18,
CMD24, CMD25, and CMD53. Values ranging from 1 up to maximum
buffer size are set. In case of memory, it is set up to 512 bytes. It is
accessed only if no transaction is in-progress (i.e., after a transaction has
stopped). Read operations during transfers return an invalid value, and
write operations are ignored.
0200h = 512 Bytes , 01FFh = 511 Bytes
……
0004h = 4 Bytes , 0003h = 3 Bytes
0002h = 2 Bytes , 0001h = 1 Byte
0000h = No data transfer
