Configuration register specifications

This card supports four Configuration registers for the purpose of the configuration and observation of this
card. These registers can be used in memory card mode and I/O card mode. In True IDE mode, these
registers can not be used.

1. Configuration Option register (Address 200H)

This register is used for the configuration of the card configuration status and for the issuing soft reset to the
card.

R/W Setting this bit to "1", places the card in the reset state (Card Hard Reset). This

operation is equal to Hard Reset, except this bit is not cleared. Then this bit set to "0",
places the card in the reset state of Hard Reset (This bit is set to "0" by Hard Reset) .
Card configuration status is reset and the card internal initialized operation starts when
Card Hard Reset is executed, so next access to the card should be the same sequence
as the power on sequence.

R/W This bit sets to "0" when pulse mode interrupt is selected, and "1" when level mode

interrupt is selected.

R/W This bits is used for select operation mode of the card as follows.

When Power on, Card Hard Reset and Soft Reset, this data is "000000" for the purpose
of Memory card interface recognition.

R This bit indicates that CRDY/-BSY bit on Pin Replacement register is set to "1". When

CHGED bit is set to "1", -STSCHG pin is held "L" at the condition of SIGCHG bit set to
"1" and the card configured for the I/O interface.

R/W This bit is set or reset by the host for enabling and disabling the status-change signal (-

STSCHG pin). When the card is configured I/O card interface and this bit is set to "1", ­STSCHG pin is controlled by CHGED bit. If this bit is set to "0", -STSCHG pin is kept
"H".

R/W The host sets this field to "1" when it can provide I/O cycles only with on 8 bit data bus

(D7 to D0).

R/W When this bit is set to "1", the card enters sleep state (Power Down mode). When this

bit is reset to "0", the card transfers to idle state (active mode). RRDY/-BSY bit on Pin
Replacement Register becomes BUSY when this bit is changed. RRDY/-BSY will not
become Ready until the power state requested has been entered. This card
automatically powers down when it is idle, and powers back up when it receives a
command.

R This bit indicates the internal state of the interrupt request. This bit state is available

whether I/O card interface has been configured or not. This signal remains true until the
condition which caused the interrupt request has been serviced. If interrupts are
disabled by the -IEN bit in the Device Control Register, this bit is a zero.

6. Idle (code: E3H or 97H): This command causes the Card to set BSY, enter the Idle mode, clear BSY and
generate an interrupt. If 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.

7. Idle Immediate (code: E1H or 95H): This command causes the Card to set BSY, enter the Idle (Read)
mode, clear BSY and generate an interrupt.

8. 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.

9. Read Buffer (code: E4H): This command enables the host to read the current contents of the card's sector
buffer.

43

HB28C048/032/016A6

10. 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.

11. 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.

12. Read Sector(s) (code: 20H, 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.

13. Read Verify Sector(s) (code: 40H or 41H): This command is identical to the Read Sectors command,
except that DRQ is never set and no data is transferred to the host .

14. Recalibrate (code: 1XH): This command is effectively a NOP command to the Card and is provided for
compatibility purposes.

15. Request Sense (code: 03H): This command requests an extended error code after command ends with an
error.

16. Seek (code: 7XH): This command is effectively a NOP command to the Card although it does perform a
range check.

17. Set Features (code: EFH): This command is used by the host to establish or select certain features.

Feature Operation

01H Enable 8-bit data transfers.
55H Disable Read Look Ahead.
66H Disable Power on Reset (POR) establishment of defaults at Soft Reset.
81H Disable 8-bit data transfers.
BBH 4 bytes of data apply on Read/Write Long commands.
CCH Enable Power on Reset (POR) establishment of defaults at Soft Reset.

18. Set Multiple Mode (code: C6H): This command enables the Card to perform Read and Write Multiple
operations and establishes the block count for these commands.

19. Set Sleep Mode (code: E6H or 99H): This command causes the Card to set BSY, enter the Sleep mode,
clear BSY and generate an interrupt.

20. Stand By (code: E2H or 96H): This command causes the Card to set BSY, enter the Sleep mode (which
corresponds to the ATA "Standby" Mode), clear BSY and return the interrupt immediately.

21. Stand By Immediate (code: E0H or 94H): This command causes the Card to set BSY, enter the Sleep
mode(which corresponds to the ATA "Standby" Mode), clear BSY and return the interrupt immediately.

44

HB28C048/032/016A6

22. Translate Sector (code: 87H): This card does not support by this command the function of determining
the exact number of times a user sector has been erased and programmed because this card always responds
with “00H”, though this command could provide information containing the desired cylinder, head and sector,
including its Logical Address, etc.

23. Wear Level (code: F5H): This command 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.

24. Write Buffer (code: E8 H): This command enables the host to overwrite contents of the Card's sector
buffer with any data pattern desired.

25. Write Long Sector (code: 32H or 33H): This command is provided for compatibility purposes and is
similar to the Write Sector(s) command except that it writes 516 bytes instead of 512 bytes.

26. Write Multiple (code: C5H): This command is similar to the Write Sectors command. Interrupts are not
presented on each sector, but on the transfer of a block which contains the number of sectors defined by Set
Multiple command.

27. Write Multiple without Erase (code: CDH): This command is similar to the Write Multiple command
with the exception that an implied erase before write operation is not performed.

28. Write Sector(s) (code: 30H or 31H): This command writes from 1 to 256 sectors as specified in the
Sector Count register. A sector count of zero requests 256 sectors. The transfer begins at the sector specified
in the Sector Number register.

29. Write Sector(s) without Erase (code: 38H): This command is similar to the Write Sector(s) command
with the exception that an implied erase before write operation is not performed.

30. Write Verify (code: 3CH): This command is similar to the Write Sector(s) command, except each sector
is verified immediately after being written.

Attention for Card Use

• In the reset or power off, all register informations are cleared.

• All card status are cleared automatically when VCC voltage turns below about 2.5V.

• Notice that the card insertion/removal should not be executed during host is active, if the card is used in

True IDE mode.

• After the card hard reset, soft reset, or power on reset, ATA reset, command applied the card cannot

access during +RDY/-BSY pin is "low" level. Flash card can’t be operated in this case.

• Card removal or power off should not be done during internal operations. When the removal or power off

occurred during internal operation, there is the possibility that data are lost.

• Before the card insertion VCC can not be supplied to the card. After confirmation that -CD1, -CD2 pins are

inserted, supply VCC to the card.

• -OE must be kept at the VCC level during power on reset in memory card mode and I/O card mode. -OE

must be kept constantly at the GND level in True IDE mode.
