MITSUBISHI STORAGE CARD

Preliminary

Check Power Mode(98h, E5h)

This command checks the power mode.

Execute Drive Diagnostic(90h)

This command performs the internal diagnostic tests

implemented by the card.

Erase Sector(s)(C0h)

This command is used to pre-erase and condition data

sectors in advance of a Write without Erase or Write

Multiple without Erase command.

Format Track(50h)

This command writes the desired head and cylinder of the

selected drive with a FFh pattern.

Identify Drive(ECh)

This command enables the host to receive parameter

information from the card. (Refer to the Identify Drive

Information table.)

Idle(97h, E3h)

This command causes the card to set BSY, enter the Idle

mode, clear BSY and generate an interrupt. If the sector

count is non-zero, the automatic power down mode is

enabled. If the sector count is zero, the automatic power

down mode is disabled.

Idle Immediate(95h, E1h)

This command causes the card to set BSY, enter the idle

mode, clear BSY and generate an interrupt.

Initialize Drive Parameters(91h)

This command allows the host to alter the number of

sectors per track and the number of heads per cylinder.

Read Buffer(E4h)

This command enables the host to read the current contents

of the card’s sector buffer.

Read Long Sector(22h, 23h)

This command is similar to the Read Sector(s) command

except the contents of the Sector Count register are ignored

and only one sector is read. The 512 data bytes and 4 ECC

bytes are read into the buffer(with no ECC correction) and

then transferred to the host.

ATA PC CARDS

Read Multiple(C4h)

This command performs similarly to the Read Sector(s)

command. Interrupt 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 Sector(s)(20h, 21h)

This command transfers data from the card to the host.

Data transfer starts at the sector specified by the Cylinder,

Head, and Sector Number registers, and proceeds for the

number of sectors specified in the Sector Count register.

Read Verify Sector(s)(40h, 41h)

This command is identical to the Read Sector(s) command,

except that DRQ is not asserted, and no data is transferred

to the host.

Recalibrate(1xh)

Although this command is supported for backward

compatibility, it has no actual function. The card will

always return good status at the completion of this

command.

Request Sense(03h)

This command requests extended error information for the

previous command.

Seek(7xh)

This command is supported for backward compatibility.

Although this command has no actual function, it does

perform a range check of valid track, and posts an IDNF

error if the Head or Cylinder specified are out of bounds.

Set Features(EFh)

This command is used by the host to establish or select

certain features.

Set Multiple Mode(C6h)

This command enables the card to perform Read and Write

Multiple operations and establishes the block count for

these commands. This card supports 1 sector block size.

Set Sleep Mode(99h, E6h)

This command causes the card to set BSY, enter the Sleep

mode, clear BSY and generate an interrupt.
