This command checks the power mode.
This command performs the internal diagnostic tests
implemented by the IDE Flash Drive. The Diagnostic Code is
returned in the Error Register.
Command is used to pre-erase/condition data sectors in advance.
Command writes the desired head/cylinder of the selected drive
with a vender unique data pattern (typically 00h or FFh). This
IDE Flash Drive accepts a sector buffer of data from the host to
follow the command with the same protocol as the Write Sector
Command although the information in the buffer is not used.
Command lets host receive parameter information from the IDE
Flash Drive in the same protocol as Read Sector(s) command.
Command causes the IDE Flash Drive to set BSY, enter the Idle
mode, clear BSY, and generate an interrupt. If sector count is
non-zero, automatic power down mode is enabled. If sector
count is zero, the automatic power down mode is disabled.
This command causes the IDE Flash Drive to set BSY, enter the
Idle mode, clear BSY, and generate an interrupt.
This command enables the host to set the number of sectors
per track and the number of heads per cylinder.
No Operation.
This command enables the host to read the current contents of
the IDE Flash Drive’s sector buffer.
Command is sector read command used for MWDMA transfer.
Command performs similarly to the Read Sectors command.
Interrupts are not generated on each sector, but on transfer of a
block which contains the number of sectors defined by a Set
Multiple command.
Command performs similarly to the Read Sector(s) command
except that it returns 516 bytes of data instead of 512 bytes.
Command reads from 1 to 256 sectors as specified in the Sector
Count register. Sector count of 0 requests 256 sectors. Transfer
begins at the sector specified in the Sector Number register.
This command verifies one or more sectors on the IDE Flash
Drive by transferring data from the flash media to the data buffer
in the IDE Flash Drive and verifying that the ECC is correct. This
command is identical to the Read Sectors command, except
that DRQ is never set and no data is transferred to the host.
The IDE Flash Drive performs only the interface timing and
register operations. When this command is issued, the IDE
Flash Drive sets BSY and waits for an appropriate length of
time, after which it clears BSY and issues an interrupt. When
this command ends normally, the IDE Flash Drive is initialized.
Command requests extended error code after command ends
with error. Extended error code is returned in the Error Register
