Code
61000-04502-109, August 2007
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.
This command is used to pre-erase and condition data sectors in
advance.
This command writes the desired head and 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.
This command lets the host receive parameter information from
the IDE Flash Drive in the same protocol as Read Sector(s)
command.
This command causes the IDE Flash Drive to set BSY, enter the
Idle mode, clear BSY, and generate an interrupt. If the sector
count is non-zero, automatic power down mode is enabled. If the
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.
This command is the sector read command used for Multiword
DMA transfer.
This command performs similarly to the Read Sectors command.
Interrupts are not generated on each sector, but on the transfer of
a block which contains the number of sectors defined by a Set
Multiple command.
This command performs similarly to the Read Sector(s) command
except that it returns 516 bytes of data instead of 512 bytes.
This command reads from 1 to 256 sectors as specified in the
Sector Count register. A sector count of 0 requests 256 sectors.
The transfer begins at the sector specified in the Sector Number
register.
