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. 

This command is identical to the Read Sector(s) EXT command, except that the device shall have read 
the data from the media, the DRQ bit is never set to one, and no data is transferred to the host. 

This command will cause the device performing a range check. 

This command performs the internal diagnostic tests implemented by the controller. 

This command will enable the host to set the number of sectors per track and the number of heads per 
cylinder. 

When this command is issued, the NSSD will report the SMART data to Host. 

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. 

This command is similar to the Write Sector(s) - 30h command. Interrupts are not presented on each 
sector, but on the transfer of a block which contains the number of sectors defined by the Set Multiple 
Mode - C6h command. 

This command enables the SSD to perform multiple Read and Write operations and establishes the 
block count for these commands. 

When this command is issued, the SSD will prepare the data, and transfer the data to host via ultra 
DMA protocol.

When this command is issued, the NSSD will prepare for receiving the data transfer from host via ultra 
DMA protocol.

This command will cause the NSSD to set BSY, enter the Standby Mode, clear BSY, and return the 
interrupt immediately. 

This command will cause the drive to set BSY, enter the IDLE (READ) mode, clear BSY, and generate 
an interrupt.
