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.
22. Translate Sector (code: 87H): This command allows the host a method of determining the exact
number of times a user sector has been erased and programmed.
23. Wear Level (code: F5H): This command is effectively a NOP command and is only implemented for
backward compatibility.
24. Write Buffer (code: E8H): This command enables the host to overwrite contents of the Card's sector
buffer with any data pattern desired.
25. Write Long Sector (code: 32H or 33H): This command is provided for compatibility purposes and is
similar to the Write Sector(s) command except that it writes 516 bytes instead of 512 bytes.
26. Write Multiple (code: C5H): This command is similar to the Write Sectors command. Interrupts are
not presented on each sector, but on the transfer of a block which contains the number of sectors
defined by Set Multiple command.
27. Write Multiple without Erase (code: CDH): This command is similar to the Write Multiple command
with the exception that an implied erase before write operation is not performed.
28. Write Sector(s) (code: 30H or 31H): This command writes from 1 to 256 sectors as specified in the
Sector Count register. A sector count of zero requests 256 sectors. The transfer begins at the sector
specified in the Sector Number register.
29. Write Sector(s) without Erase (code: 38H): This command is similar to the Write Sector(s) command
with the exception that an implied erase before write operation is not performed.
30. Write Verify (code: 3CH): This command is similar to the Write Sector(s) command, except each
sector is verified immediately after being written.
