8/16-bit Data Bus CompactFlash 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.

CompactFlash 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.
