WRITE DMA (CAh)
Write data to sectors during Ultra DMA and Multiword DMA transfer. Use the SET FEATURES command to specify
the mode value.
WRITE MULTIPLE (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.
WRITE SECTOR(S) (30h)
Write data to a specified number of sectors (1 to 256, as specified with the Sector Count register) from the specified
address. Specify “00h” to write 256 sectors.
NOP (00h)
The device shall respond with command aborted. For devices implementing the Overlapped feature set, subcommand
code 00h in the Features register shall abort any outstanding queue. Subcommand codes 01h through FFh in the
Features register shall not affect the status of any outstanding queue.
READ BUFFER (E4h)
The READ BUFFER command enables the host to read a 512-byte block of data.
WRITE BUFFER (E8h)
This command enables the host to write the contents of one 512-byte block of data to the device’s buffer.
 Power Management Feature Set
CHECK POWER MODE (E5h or 98h)
The host can use this command to determine the current power management mode.
IDLE (E3h or 97h)
This command causes the device to set BSY, enter the Idle mode, clear BSY and generate an interrupt. If sector count
is non-zero, the automatic power down mode is enabled. If the sector count is zero, the automatic power mode is
disabled.
IDLE IMMEDIATE (E1h or 95h)
This command causes the device to set BSY, enter the Idle(Read) mode, clear BSY and generate an interrupt.
SLEEP (E6h or 99h)
This command causes the device to set BSY, enter the Sleep mode, clear BSY and generate an interrupt.
STANDBY (E2h or 96h)
This command causes the device to set BSY, enter the Sleep mode (which corresponds to the ATA “Standby”
Mode), clear BSY and return the interrupt immediately.
STANDBY IMMEDIATE (E0h or 94h)
This command causes the drive to set BSY, enter the Sleep mode (which corresponds to the ATA “Standby” Mode),
clear BSY and return the interrupt immediately.
