Read DMA Queued (C7h)
This command is mandatory for devices that implement the TCQ feature set. The command is similar
in function to the Read DMA (C8h) command. The device may release or execute the data transfer
without performing a release if the data is ready to transfer.
Read DMA Queued Ext (26h)
This command is mandatory for devices that implement the TCQ and 48-bit feature sets. The
command is similar in function to the Read DMA (C8h) command. The device may release or execute
the data transfer without performing a release if the data is ready to transfer.
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.
Read Multiple Extended (29h)
This command is mandatory for all devices that implement the 48-bit Address feature set. The
command will read the number of logical sectors specified in the Count field. The number of logical
sectors determines the DRQ data block count, which in turn will determine the number of logical
sectors that are to be transferred.
Read Sector(s) (20h)
This command will read from 1 to 256 sectors as specified in the Sector Count Register. A sector
count of 0 (zero) requests 256 sectors. The transfer will begin at the sector specified in the Sector
Number Register.
Read Sector(s) Extended (24h)
This command is mandatory for devices that implement the 48-bit Address feature set. This
command will read from 1 to 256 to 65,536 logical sectors as specified in the Sector Count Register.
A sector count of 0 (zero) will request 65,536 logical sectors. The transfer will begin at the sector
specified in the LBA field.
Read/Verify Sector(s) (40h)
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.
Read/Verify Extended (42h)
This command is mandatory for devices that implement the 48-bit Address feature set. The command
is identical to the Read Sector(s) Extended (24) command, except that no data is transferred from
the device to the host. The device will read the data stored in the media and verify that no errors exist.
