Check Power Mode
(code: E5h or 98h)
This command checks the power mode.
Execute Drive Diagnostic
(code: 90h)
This command performs the internal diagnostic tests
implemented by the module. See ERROR register for
dianostic codes.
Erase Sector(s)
(code: C0h)
This command is used to pre-erase and condition data
sectors in advance.
Format Track
(code: 50h)
This command writes the desired head and cylinder of the
selected drive with a vender unique data pattern (typically
00h or FFh). This 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.
Identify Drive
(code: ECh)
This command enables the host to receive parameter
information from the module. (See tables on the next
page.)
Idle
(code: E3h or 97h)
This command causes the module 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.
Idle Immediate
(code: E1h or 95h)
This command causes the module to set BSY, enter the
Idle (Read) mode, clear BSY, and generate an interrupt.
Initialize Drive Parameters
(code: 91h)
This command enables the host to set the number of
sectors per track and the number of heads per cylinder.

Read Buffer
(code: E4h)
This command enables the host to read the current
contents of the module’s sector buffer.
Read Multiple
(code: C4h)
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.
Read Long Sector
(code: 22h or 23h)
This command performs similarly to the Read Sector(s)
command except that it returns 516 bytes of data instead
of 512 bytes.
Read Sector(s)
(code: 20h or 21h)
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.
Read Verify Sector(s)
(code: 40h or 41h)
This command verifies one or more sectors on the module
by transferring data from the flash media to the data
buffer in the 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.
Recalibrate
(code: 1Xh)
The module performs only the interface timing and
register operations. When this command is issued, the
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 module is
initialized.
