This command is effectively a NOP command to the IDE Flash
Drive although it does perform a range check.
Command is used by host to establish or select certain features.
Command enables IDE Flash Drive to perform multiple r/w
operations and establishes block count for r/w commands.
This is the only command that allows the host to set the IDE
Flash Drive into Sleep mode. When the IDE Flash Drive is set to
sleep mode, the IDE Flash Drive clears the BSY line and issues
an interrupt. The IDE Flash Drive enters sleep mode and the
only method to make the IDE Flash Drive active again (back to
normal operation) is by performing a hardware reset or a
software reset.
Command sets IDE Flash Drive in Standby mode. If Sector
Count Register is value other than 0H, Auto Power Down is
enabled and when IDE Flash Drive returns to the idle mode,
timer starts a countdown. Time is set in Sector Count Register.
This command causes the IDE Flash Drive to set BSY, enter the
Standby mode, clear BSY and return the interrupt immediately.
This command allows the host a method of determining the
exact number of times a user sector has been erased and
programmed. This command is not supported.
This command is effectively a NOP command and only
implemented for backward compatibility. The Sector Count
Register will always be returned with an 00h indicating Wear
Level is not needed.
This command enables the host to overwrite the contents of the
IDE Flash Drive’s sector buffer with any data pattern desired.
This command is the sector write command used for Multiword
DMA transfer.
This command is provided for compatibility purposes and is
similar to the Write Sector(s) command except that it writes 516
bytes instead of 512 bytes.
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.
This command is similar to the Write Multiple command, except
that an implied erase before the write operation is not
performed.
Note: Before using this command, it is required to erase the
respective sectors using the Erase Sectors command
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.
This command is similar to the Write Sector(s) command,
except that an implied erase before the write operation is not
performed.
Note: Before using this command, it is required to erase the
respective sectors using the Erase Sectors command.
This command is similar to the Write Sector(s) command except
each sector is verified immediately after being written.
