Transfer Byte Number Count Register (TBCR)
TBCR specifies the number of bytes to be transferred (block size) for a block transfer command.
The block size is the number of data block bytes not including the start bit (byte in SPI mode) and
CRC. The multiblock transfer command in MMC mode corresponds to the number of bytes of
each data block. This register setting is ignored in the stream transfer command in MMC mode.

Transfer Block Number Counter (TBNCR)
TBNCR sets the number of blocks to be transferred when multiblock transfer is specified by bit
TY5 in CMDTYR. The contents of TBNCR is decremented for every 1-block transfer completion.
When the contents of TBNCR is 0, the command sequence is terminated, and an interrupt is
generated.
