10. Read Multiple (code: C4H): This command performs similarly to the Read Sectors command.
Interrupts are not generated on each sector, but on the transfer of a block which contains the number of
sectors defined by a Set Multiple command.
11. Read Long Sector (code: 22H or 23H): This command performs similarly to the Read Sector(s)
command except that it returns 516 bytes of data instead of 512 bytes.
12. Read Sector(s) (code: 20H, 21H): This command reads from 1 to 256 sectors as specified in the Sector
Count register. A sector count of 0 requests 256 sectors. The transfer begins at the sector specified in the
Sector Number register.
13. Read Verify Sector(s) (code: 40H or 41H): This command is identical to the Read Sectors command,
except that DRQ is never set and no data is transferred to the host .
14. Recalibrate (code: 1XH): This command is effectively a NOP command to the Card and is provided for
compatibility purposes.
15. Request Sense (code: 03H): This command requests an extended error code after command ends with an
error.
16. Seek (code: 7XH): This command is effectively a NOP command to the Card although it does perform a
range check.
17. Set Features (code: EFH): This command is used by the host to establish or select certain features.

18. Set Multiple Mode (code: C6H): This command enables the Card to perform Read and Write Multiple
operations and establishes the block count for these commands.
19. Set Sleep Mode (code: E6H or 99H): This command causes the Card to set BSY, enter the Sleep mode,
clear BSY and generate an interrupt.
20. Stand By (code: E2H or 96H): This command causes the Card to set BSY, enter the Sleep mode (which
corresponds to the ATA "Standby" Mode), clear BSY and return the interrupt immediately.
21. Stand By Immediate (code: E0H or 94H): This command causes the Card to set BSY, enter the Sleep
mode(which corresponds to the ATA "Standby" Mode), clear BSY and return the interrupt immediately.
