Transfer Byte Number Count Register (TBCR)
TBCR is an 8-bit readable/writable register that specifies the number of bytes to be transferred
(block size) for each single block transfer command. TBCR specifies the number of data block
bytes not including the start bit, end bit, and CRC.
The multiple block transfer command corresponds to the number of bytes of each data block. This
setting is ignored by the stream transfer command.
