This command will verify one or more sectors by transferring data from the flash media to the data
buffer and verifying the ECC is correct. The command is identical to the Read Sector(s) - 20h
command except that DRQ is never set and no data is transferred to the host.

(B0h)
When this command is issued, the NSSD will report the SMART data to Host.
5.2.16 Read
Multiple
(C4h)
This command is similar to the Read Sector(s) -20h command. Interrupts are not generated on each
sector, but on the transfer of a block that contains the number of sectors as defined by a Set Multiple
Mode - C6h command.
