transferred for each interrupt.
The default block size after power up is 0, and Read Multiple and Write Multiple commands are

disabled.
If an invalid block size is specified, an Abort error will be returned to the host, and Read Multiple
and Write Multiple commands will be disabled.

The block size to be used for Read Multiple and Write Multiple commands. Valid
block sizes can be selected from 0, 1, 2, 4, 8 or 16. If 0 is specified, then Read Multiple
