The Set Multiple command enables the device to perform Read and Write Multiple commands and establishes the
block size for these commands. The block size is the number of sectors to be transferred for each interrupt.
The default block size after power up, or hard reset 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.
Output Parameters To The Device
Sector Count
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
and Write Multiple commands are disabled.
