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.
This command requests an extended error code after a command
ends with an error. The extended error code is returned in the
Error Register
This command is effectively a NOP command to the IDE Flash
Drive although it does perform a range check.
This command is used by the host to establish or select certain
features.
This command enables the IDE Flash Drive to perform multiple
read and write operations and establishes the block count for
these 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.
This command sets the IDE Flash Drive in Standby mode. If the
Sector Count Register is a value other than 0H, an Auto Power
Down is enabled and when the IDE Flash Drive returns to the idle
mode, the timer starts a countdown. The time is set in the 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.
