32. SET MULTIPLE MODE (code: C6h): This command enables the Disk to perform READ and Write
Multiple operations and establishes the block count for these commands.
33. SLEEP ( code: 99h or E6h ): This command causes the Disk to set BSY, enter the Sleep mode, clear
BSY and generate an interrupt.
34. SMART ENABLE/DISABLE AUTO SAVE (code: B0h): This command enables and disables the
optional attribute auto save feature of the device.
35. SMART ENABLE OPERATIONS (code: B0h): This command enables access to all SMART
capabilities within the device.
36. SMART DISABLE OPERATIONS (code: B0h): This command disables all SMART capabilities
within the device.
37. SMART RETURN STATUS (code: B0h): This command causes the device return the reliability status
of the device to the host.
38. STANDBY (code: 96h or E2h): This command causes the Disk to set BSY, enter the Sleep mode
(which corresponds to the ATA "Standby" Mode), clear BSY and return the interrupt immediately.
39. STANDBY IMMEDIATE (code: 94h or E0h): This command causes the Disk to set BSY, enter the
Sleep mode (which corresponds to the ATA "Standby" Mode), clear BSY and return the interrupt
immediately.
40. WRITE BUFFER (code: E8h): This command enables the host to overwrite contents of the Disk's
sector buffer with any data pattern desired.
41. WRITE DMA (code: CAh or CBh): This command writes from 1 to 256 sectors as specified in the
Sector Count register using the DMA data transfer protocol. A sector count of 0 requests 256 sectors. The
transfer begins at the sector specified in the Sector Number register.
42. 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.
43. WRITE LONG SECTOR (code: 32h or 33h): This command is provided for compatibility purposes
and nearly performs one sector WRITE SECTOR command except that it transfers the data and 4 bytes
appended to the sector. These appended 4 bytes are not written on the flash memories.
44. WRITE SAME (code: E9h): This command nearly performs one sector WRITE SECTOR command
except that only one sector of data transferred. The Sector Counter Register value means one sector data write
counts. (ex: value is 5 to nearly fifth one sector write execute.)
45. 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.
