Features 01h and 81h are used to enable and clear 8 bit data transfer modes in True IDE Mode. If the 01h
feature command is issued all data transfers shall occur on the low order D[7:0] data bus and the -IOIS16
signal shall not be asserted for data register accesses. The host shall not enable this feature for DMA
transfers.
Features 02h and 82h allow the host to enable or disable write cache in SSD that implement write cache.
When the subcommand disable write cache is issued, the SSD shall initiate the sequence to flush cache to
non-volatile memory before command completion.
Feature 03h allows the host to select the PIO or Multiword DMA transfer mode by specifying a value in the
Sector Count register. The upper 5 bits define the type of transfer and the low order 3 bits encode the mode
value. One PIO mode shall be selected at all times. For Cards which support DMA, one DMA mode shall be
selected at all times. The host may change the selected modes by the Set Features command.

Notes: Multiword DMA is not permitted for devices configured in the PC Card Memory or the PC Card I/O
interface mode.
If a SSD supports PIO modes greater than 0 and receives a Set Features command with a Set Transfer Mode
parameter and a Sector Count register value of “00000000b”, it shall set its default PIO mode. If the value
is “00000001b” and the SSD supports disabling of IORDY, then the SSD shall set its default PIO mode and
disable IORDY. A SSD shall support all PIO modes below the highest mode supported, e.g., if PIO mode 1 is
supported PIO mode 0 shall be supported.
Support of IORDY is mandatory when PIO mode 3 or above is the current mode of operation.
A SSD reporting support for Multiword DMA modes shall support all Multiword DMA modes below the highest
mode supported. For example, if Multiword DMA mode 2 support is reported, then modes 1 and 0 shall also
be supported. Note that Multiword DMA shall not be supported while PC Card interface modes are selected.
A SSD reporting support for Ultra DMA modes shall support all Ultra DMA modes below the highest mode
supported. For example, if Ultra DMA mode 2 support is reported then modes 1 and 0 shall also be
supported.
If an Ultra DMA mode is enabled, any previously enabled Multiword DMA mode shall be disabled by the
device. If a Multiword DMA mode is enabled any previously enabled Ultra DMA mode shall be disabled by
the device. Feature 05h allows the host to enable Advanced Power Management. To enable Advanced Power
Management, the host writes the Sector Count register with the desired advanced power management level
and then executes a Set Features command with subcommand code 05h. The power management level is a
scale from the lowest power consumption setting of 01h to the maximum performance level of Feh.
Table 70: Advanced power management levels shows these values.
Table 70: Advanced power management levels
In the current version the advanced power management levels are accepted, but don’t influence
performance and power consumption.
Device performance may increase with increasing power management levels. Device power consumption
may increase with increasing power management levels. The power management levels may contain
discrete bands. For example, a device may implement one power management method from 80h to A0h
and a higher performance, higher power consumption method from level A1h to Feh. Advanced power
management levels 80h and higher do not permit the device to spin down to save power.
