1 Introduction
1.1 Overview
RecaData's PATA SSD (Solid State Drive) is a high performance and high reliability storage device
based on NAND Flash technology that designed to solve the bottleneck of computing system by traditional
hard disk drives. RecaData’s PATA SSD doesn't have a moving parts and it has the same host interface and
physical dimension with Hard Disk Drive, so it can be drop-in replaced with the hard disk drives without
anything. With a high performance and low power consumption, RecaData’s PATA SSD can be a good
storage device for NB and Tabletop PC.
RecaData’s PATA SSD purely consists of semiconductor devices and NAND flash memories, which give
rugged features against shock and vibration, uses in extreme environment such as industrial PC an increased
MTBF. Further more, RecaData’s PATA SSD has highly advanced flash memory management algorithm to
guarantee higher performance and data integrity.

Table 11 ATA commands list
6.2 ATA Commands Specifications
 CHECK POWER MODE(E5h)
The host can use this command determine the current power management mode
 EXECUTE DIAGNOSTICS(90h)
This command performs the internal diagnostic tests implemented by the drive.See error
register for diagnostic mode
 FLUSH CACHE(E7h)
This command is used by the host to request the device to flush the write cache.If there is data

Aug,2012
in the write cache,that data shall be written to the media.The BSY bit should remain set to one
until all data has been written or an error occurs.
 INDENTIFY DEVICE(Ech)
This commands read out 512Bytes of the drive parameter information.Parameter information
consists of the arrangement and value as shown in the follow table.This command enables the
host to receive the identify drive information from the device.
 IDLE(E3h)
This command causes the device set BSY, enter the Idle mode,clear BSY and generate an
interrupt.If sectors is non-zero,the automatic power down mode is enable.If the sectors is
zero,the automatic power down mode is disable.
 IDLE IMMEDIATE(E1h)
This command causes the device set BSY,enter the Idle(read) mode,clear BSY and generate
an interrupt.
 INITIALIZE DEVICE PARAMETER(91h)
This command enables the host to set the number of sectors per track and the number of
tracks per heads.
 READ DMA(C8h)
Read data from sectors during Ultra DMA and Multiword DMA transfer.Use the SET
FEATURES command to specify the mode value. A sector count of zero requests 256 sectors.
 READ MULTIPLE(C4h)
This command performs similarly to the Read Sector command.Interrupts are not generate 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 or 21h)
This command reads 1 to 256 sectors as specified in the sector count register from sectors
which is set by Sector number register.A sector count of zero requests 256 sectors.The
transfer being specified in the Ssector Nnumber register.
 READ VERIFY SECTOR(S)(40h or 41h)
This command verifies one or more sectors on the device by transferring data from the flash
media on the data buffer in the drive 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(10h)
The current drive performs no processing if it receives this command.It’s supported for
backward compatibility with previous devices.
 SECURITY DISABLE PASSWORD(F6h)
Disable any previously set user password and cancels the lock.The host transfers 512Bytes
data,as shown in the following table, to the device.The transferred data contains a user or
master password,which the device compares with the saved password.If they match,the
device cancels the lock.The master password is still saved.It’s re-enabled issuing the
SECURITY SET PASSWORD command to re-set a user password.
 SECURITY ERASE PREPARE(F3h)
This command shall be issued immediately before the Security Erase Unit command to enable

Aug,2012
erasing and unlocking.This command prevents accidental lost data on the device.
 SECURITY ERASE UNIT(F4h)
The host uses this command to transfer 512Bytes data,as shown in the following table,to the
drive.The transferred data contains a user or master password,which the device compares
with the saved password.If they match,the device delete the user data,disable the user
password,and cancels the lock. The master password is still saved.It’s re-enabled by issusing
the SECURITY SET PASSWORD command to re-set a user password.
 SECURITY FREEZE LOCK(F5h)
Caused the device enter FROZEN mode.Once this command has been executed,the following
commands to update a lock result in the Aborted Command error:
 SECURITY SET PASSWORD
 SECURITU UNLOCK
 SECURITU DIABLE PASSWORD
 SECURITY ERASE PREPARE
 SECURITY ERASE UNIT
The drive exits from the FROZEN mode upon a power-off or hard reset.If the SECURITY
FREEZE LOCK command issued when the device is placed in FROZEN mode,the drive
execute the command,staying FROZEN mode.
 SECURITY SET PASSWORD(F1h)
This command set user password or master password.The host outputs sector data with PIO
data-out protocol to indicate the information defined in the following table.
 SECURITY UNLOCK(F2h)
This command disabled LOCKED MODE of the device.This command transfers 512Bytes data
from the host with PIO data-out protocol.The following table defines the content of this
information.
 SEEK(7xh)
This command effectively a NOP command to the device although it dose perform a range
check.
 SET FEATURES(EFh)
This command set parameter to Features register and set drive operation. For
transfer mode, parameter is set to Sector Count register. This command is used by the
host to establish or select certain features.

Table 12 Features register Value and settable operating mode
 SET MULTIPLE MODE(C6h)
This command enables the device to perform READ MULTIPLE and WRITE MULTIPLE
operations and establishes the block count of these commands.
 SLEEP(E6h)
This command causes the device to set BSY,enter the sleep mode,clear BSY and generation

an interrupt.
 SMART(B0h)
Performs different processing required for predicting device failures, according to the
subcommand specified in the Features register. If the Features register contains an
unsupported value, the Aborted Command error is returned. If the SMART function is
disabled, any subcommand other than SMART ENABLE OPERATIONS results in the
Aborted Command error.
 STANDBY(E2h)
This command causes the device to set BSY, enter the Sleep mode (which
corresponds to the ATA!Standby Mode), clear BSY and return the interrupt immediately.
 STANDBY IMMEDIATE(E0h)
This command causes the drive to set BSY, enter the Sleep mode (which corresponds
to the ATA !Standby Mode), clear BSY and return the interrupt immediately.
 WRITE DMA((CAh or CBh)
Write data to sectors during Ultra DMA and Multiword DMA transfer. Use the SET
FEATURES command to specify the mode value.
 WRITE MULTIPLE(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.
 WRITE SECTOR(S) (30h or 31h)
Write data to a specified number of sectors (1 to 256, as specified with the Sector
Count register) from the specified address. Specify "00h"– to write 256 sectors
