Code
61000-04498-112, April 2008
This command checks the power mode.
Command performs the internal diagnostic tests implemented
by the Disk Module. Diagnostic Code is returned in 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
Disk Module 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 the host receive parameter information from the
Disk Module in the same protocol as Read Sector(s) command.
Command causes the Disk Module 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 Disk Module 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 Disk Module’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 Disk Module
by transferring data from the flash media to the data buffer in the
Disk Module 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 Disk Module performs only the interface timing and register
operations. When this command is issued, the Disk Module 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 Disk Module is initialized.
Command requests extended error code after command ends
with error. Extended error code is returned in the Error Register
This command is effectively a NOP command to the Disk
Module although it does perform a range check.
