The ATA Flash Disk Controller recognizes the control, address, and data signals on the ATA/IDE bus and translates them into memory accesses to the standard NAND-type flash media. The SST55LD019A/B/C device supports Single Level Cell (SLC) flash media. This technology suits solid state mass storage applications offering new, expanded functionality while enabling smaller, lighter designs with lower power consumption. Utilizing SST’s proprietary SuperFlash memory technology, the ATA Flash Disk Controller is factory pre-programmed with an embedded flash file system which, upon initial Power-on, recognizes the attached flash media devices, sets up a bad block table, executes all necessary handshaking routines for flash media support, and, finally, performs the low-level format. This process typically takes about 3 sec + 0.5 sec/GByte of drive capacity, allowing a 2 GByte flash drive to be fully initialized in about 4 seconds. The ATA/IDE interface is widely used in such products as portable and desktop computers, digital cameras, music players, handheld data collection scanners, PDAs, handy terminals, personal communicators, audio recorders, monitoring devices, and set-top boxes. SST’s ATA Flash Disk Controller supports standard ATA/IDE protocol with up to PIO Mode-4 and Multi-word DMA Mode-2 interface. This technology enables a very fast, completely seamless integration of flash drives into an embedded design. For added manufacturing flexibility, system debug, re-initialization, and user customization can be accomplished either through the ATA/IDE interface, for ATA Disk Module or flash drive products, or through the Serial Communication Interface (SCI), for fully embedded ATA Flash Disk Con- ©2006 Silicon Storage Technology, Inc.

S71241-04-000 5 12/06 ATA Flash Disk Controller SST55LD019A / SST55LD019B / SST55LD019C Data Sheet 1.0 GENERAL DESCRIPTION 1.1.5 Embedded Flash File System The ATA Flash Disk Controller contains a microcontroller and embedded flash file system integrated in TQFP and TFBGA packages. Refer to Figure 2-1 for the ATA Flash Disk Controller block diagram. The controller interfaces with the host system allowing data to be written to and read from the flash media. The embedded flash file system is an integral part of the ATA Flash Disk Controller. It contains MCU firmware that performs the following tasks: 1. Translates host side signals into flash media writes and reads. 1.1 Performance-optimized ATA Flash Disk Controller 2. Provides dynamic flash media wear leveling to spread the flash writes across all unused memory address space to increase the longevity of flash media. The heart of the flash drive is the ATA Flash Disk Controller which translates standard ATA signals into flash media data and control signals. The following components contribute to the ATA Flash Disk Controller’s operation. 3. Keeps track of data file structures. 4. Manages system security for the selected protection zones. 1.1.1 Microcontroller Unit (MCU) The MCU translates ATA/IDE commands into data and control signals required for flash media operation. 1.1.6 Error Correction Code (ECC) The ATA Flash Disk Controller utilizes 72-bit ReedSolomon Error Detection Code (EDC) and Error Correction Code (ECC), which provides the following error immunity for each 512-byte block of data: 1.1.2 Internal Direct Memory Access (DMA) The ATA Flash Disk Controller uses internal DMA allowing instant data transfer from buffer to flash media. This implementation eliminates microcontroller overhead associated with the traditional, firmware-based approach, thereby increasing the data transfer rate. 1. Corrects up to three random 12-bit symbol errors. 2. Corrects single bursts up to 25 bits. 3. Detects single bursts up to 61 bits and double bursts up to 15 bits. 1.1.3 Power Management Unit (PMU) 4. Detects up to six random 12-bit symbol errors. The power management unit controls the power consumption of the ATA Flash Disk Controller. The PMU dramatically reduces the power consumption of the ATA Flash Disk Controller by putting the part of the circuitry that is not in operation into sleep mode. 1.1.7 Serial Communication Interface (SCI) The Serial Communication Interface (SCI) is designed to enable the user to restart the self-initialization process and to customize the drive identification information. 1.1.4 SRAM Buffer 1.1.8 Multi-tasking Interface A key contributor to the ATA Flash Disk Controller performance is an SRAM buffer. The buffer optimizes the host’s data transfer to and from the flash media.

S71241-04-000 15 12/06 ATA Flash Disk Controller SST55LD019A / SST55LD019B / SST55LD019C Data Sheet 5.0 MANUFACTURING SUPPORT The ATA Flash Disk controller firmware contains a list of supported standard NAND flash media devices. Upon initial Poweron, the controller scans all connected flash media devices and reads their device ID. If the device ID matches the listed flash media devices in the ATA Flash Disk controller, the controller performs drive recognition based on the algorithm provided by the flash media suppliers, including setting up the bad block table, executing all the necessary handshaking routines for flash media support, and, finally, performing the low-level format. For Power-up timing specifications, please refer to Table 12-4. Please contact SST for the most current list of supported NAND Flash media devices. In the event that the NAND flash media device ID is not recognized by the ATA Flash Disk controller, the user has an option of adding this device to the controller device table through the manufacturing interface provided by SST. Please contact SST for the ATA Flash Disk controller manufacturing interface software. If the drive initialization fails, and a visual inspection is unable to determine the problem, the SST55LD019A / SST55LD019B / SST55LD019C ATA Flash Disk controller provides a comprehensive interface for manufacturing flow debug. This interface not only allows debug of the failure and manual reset of the initialization process, but also allows customization of user definable options. 5.1 ATA/IDE Interface The ATA Flash Disk controller interface can be used for manufacturing support. SST provides an example of a DOS-based solution (an executable routine downloadable from SST’s web site) for manufacturing debug and rework. 5.2 Serial Communication Interface (SCI) For additional manufacturing flexibility, the SCI bus can be used for manufacturing error reporting. The SCI consists of 3 active signals: SCIDOUT, SCIDIN, and SCICLK. 6.0 EXTERNAL CLOCK INTERFACE The external clock interface allows ATA Flash Disk controller operation from an external clock source generated by an RC circuit. Do not use a free running clock as input to the EXTCLKIN pin; an RC circuit must be used. Contact SST for reference circuit and recommended external clock settings. While the controller has an internal clock source, the external clock source allows slowing of the system clock operation to limit the peak current and overcome additional bus loading. The external clock interface consists of three signals: INTCLKEN, EXTCLKIN, and EXTCLKOUT. The INTCLKEN pin selects between external and internal clock sources for the ATA Flash Disk controller. If this pin is pulled high before device Power-on, then the internal clock source is selected; otherwise, the external clock source is selected. The EXTCLKIN and EXTCLKOUT signals are the input and output clock signals, respectively. 7.0 SECURITY FEATURES The SST55LD019A/B/C ATA Flash Disk Controller offers added data protection for applications where data security is of the utmost importance. The secure features are: 1. Protection zones - Customer can enable up to 4 independent protection zones, with two options: Read-only or Hidden (Read and Write protected) within each protected zone. If protection zones are not enabled the data is unprotected (default configuration). 2. Password protection - Accessing information within the protected zones can be only achieved through a customer-unique password. 3. Purge command - The system can issue a Purge command to erase all information stored in the flash media. ©2006 Silicon Storage Technology, Inc. S71241-04-000 16 12/06 ATA Flash Disk Controller SST55LD019A / SST55LD019B / SST55LD019C Data Sheet 8.0 CONFIGURABLE WRITE PROTECT/POWER-DOWN MODES The WP_PD# pin can be used for either Write Protect mode or Power-down mode, but only one mode is active at any time. Either mode can be selected through the host command, Set-WP_PD#-Mode, explained in Section 11.2.1.31. Once the mode is set with this command, the device will stay in the configured mode until the next time this command is issued. Power-off or reset will not change the configured mode. 8.1 Write Protect Mode When the device is configured in the Write Protect mode, the WP_PD# pin offers extended data protection. This feature can be either selected through a jumper or host logic to protect the stored data from inadvertent system writes or erases, and viruses. The Write Protect feature protects the full address space of the data stored on the flash media. In the Write Protect mode, the WP_PD# pin should be asserted prior to issuing the destructive commands: Erase-Sector, Format-Track, Write-DMA, Write-Long-Sector, Write-Multiple, Write-Multiple-without-Erase, Write-Sector(s), Write-Sectorwithout-Erase, or Write-Verify. This will force the ATA Flash Disk Controller to reject any destructive commands from the ATA interface. All destructive commands will return 51H in the Status register and 04H in the Error register signifying an invalid command. All non-destructive commands will be executed normally. 8.2 Power-down Mode When the device is configured in the Power-down mode, if the WP_PD# pin is asserted during a command, the ATA disk controller completes the current command and returns to the standby mode immediately to save power. Afterwards, the device will not accept any other commands.

These registers are often collectively referred to as the Task File registers. The registers are only selectable through CS3FX#, CS1FX#, and A2-A0 signals. 11.1.2.1 Data Register (Read/Write) This 16-bit register is used to transfer data blocks between the device data buffer and the host. It is also the register through which sector information is transferred on a Format-Track command. Data transfer can be performed in PIO mode. 11.1.2.2 Error Register (Read Only) This register contains additional information about the source of an error when an error is indicated in bit 0 of the Status register. The bits are defined as follows: D7 D6 D5 D4 D3 D2 D1 D0 Reset Value BBK UNC 0 IDNF 0 ABRT 0 AMNF 0000 0000b Symbol Function BBK This bit is set when a Bad Block is detected. UNC This bit is set when an Uncorrectable Error is encountered. IDNF The requested sector ID is in error or cannot be found. ABRT This bit is set if the command has been aborted because of an ATA Flash Disk Controller status condition: (Not Ready, Write Fault, etc.) or when an invalid command has been issued. It is required that the host retry any media access command (such as ReadSectors and Write-Sectors) that ends with an error condition. AMNF This bit is set in case of a general error. ©2006 Silicon Storage Technology, Inc. S71241-04-000 20 12/06 ATA Flash Disk Controller SST55LD019A / SST55LD019B / SST55LD019C Data Sheet 11.1.2.3 Feature Register (Write Only) This register provides information regarding features of the ATA Flash Disk Controller that the host can utilize. 11.1.2.4 Sector Count Register This register contains the numbers of sectors of data requested to be transferred on a Read or Write operation between the host and the ATA Flash Disk Controller. If the value in this register is zero, a count of 256 sectors is specified. If the command was successful, this register is zero at command completion. If not successfully completed, the register contains the number of sectors that need to be transferred in order to complete the request. 11.1.2.5 Sector Number (LBA 7-0) Register This register contains the starting sector number or bits 7-0 of the Logical Block Address (LBA) for any ATA Flash Disk Controller data access for the subsequent command. 11.1.2.6 Cylinder Low (LBA 15-8) Register This register contains the low order 8 bits of the starting cylinder address or bits 15-8 of the Logical Block Address. 11.1.2.7 Cylinder High (LBA 23-16) Register This register contains the high order bits of the starting cylinder address or bits 23-16 of the Logical Block Address. 11.1.2.8 Drive/Head (LBA 27-24) Register The Drive/Head register is used to select the drive and head. It is also used to select LBA addressing instead of cylinder/ head/sector addressing. The bits are defined as follows: D7 D6 D5 D4 D3 D2 D1 D0 Reset Value 1 LBA 1 DRV HS3 HS2 HS1 HS0 1010 0000b Symbol Function LBA LBA is a flag to select either Cylinder/Head/Sector (CHS) or Logical Block Address mode (LBA). When LBA=0, Cylinder/Head/Sector mode is selected. When LBA=1, Logical Block Address is selected. In Logical Block mode, the Logical Block Address is interpreted as follows: LBA7-LBA0: Sector Number register D7-D0. LBA15-LBA8: Cylinder Low register D7-D0. LBA23-LBA16: Cylinder High register D7-D0. LBA27-LBA24: Drive/Head register bits HS3-HS0. DRV DRV is the drive number. When DRV=0 (Master), Master is selected. When DRV=1 (Slave), Slave is selected. HS3 When operating in the Cylinder, Head, Sector mode, this is bit 3 of the head number. It is Bit 27 in the Logical Block Address mode. HS2 When operating in the Cylinder, Head, Sector mode, this is bit 2 of the head number. It is Bit 26 in the Logical Block Address mode. HS1 When operating in the Cylinder, Head, Sector mode, this is bit 1 of the head number. It is Bit 25 in the Logical Block Address mode. HS0 When operating in the Cylinder, Head, Sector mode, this is bit 0 of the head number. It is Bit 24 in the Logical Block Address mode. ©2006 Silicon Storage Technology, Inc.

Reading the Status register does clear a pending interrupt while reading the alternate Status register does not. The meaning of the status bits are described as follows: D7 D6 D5 D4 D3 D2 D1 D0 Reset Value BUSY RDY DWF DSC DRQ CORR 0 ERR 1000 0000b Symbol Function BUSY The busy bit is set when the ATA Flash Disk Controller has access to the command buffer and registers and the host is locked out from accessing the Command register and buffer. No other bits in this register are valid when this bit is set to a 1. RDY RDY indicates whether the device is capable of performing ATA Flash Disk Controller operations. This bit is cleared at power up and remains cleared until the ATA Flash Disk Controller is ready to accept a command. DWF This bit, if set, indicates a write fault has occurred. DSC This bit is set when the ATA Flash Disk Controller is ready. DRQ The Data-Request bit is set when the ATA Flash Disk Controller requires that information be transferred either to or from the host through the Data register. CORR This bit is set when a correctable data error has been encountered and the data has been corrected. This condition does not terminate a multi-sector Read operation. ERR This bit is set when the previous command has ended in some type of error. The bits in the Error register contain additional information describing the error. It is required that the host retry any media access command (such as Read-Sectors and Write-Sectors) that end with an error condition. 11.1.2.10 Device Control Register (Write Only) This register is used to control the ATA Flash Disk Controller interrupt request and to issue a software reset. This register can be written to even if the device is busy. The bits are defined as follows: D7 D6 D5 D4 D3 D2 D1 D0 Reset Value X X X X 1 SW Rst -IEn 0 0000 1000b Symbol Function SW Rst This bit is set to 1 in order to force the ATA Flash Disk Controller to perform a software Reset operation. The chip remains in reset until this bit is reset to ‘0.’ -IEn 0: The Interrupt Enable bit enables interrupts 1: Interrupts from the ATA Flash Disk Controller are disabled This bit is set to 0 at Power-on and Reset. ©2006 Silicon Storage Technology, Inc.

This field defines, in nanoseconds, the minimum cycle time per word during a single sector host transfer while performing a multiple sector READ DMA or WRITE DMA command for any location on the media under nominal conditions. If a host runs at a faster cycle rate by operating at a cycle time of less than this value, the ATA Flash Disk Controller may negate DMARQ for flow control. The rate at which DMARQ is negated could result in reduced throughput despite the faster cycle rate. Transfer at this rate does not ensure that flow control will not be used, but implies that higher performance may result. SST’s ATA Flash Disk Controller supports up to Multi-word DMA Mode-2, so this field is set to 120 ns. 11.2.1.6.24 Word 67: Minimum PIO Transfer Cycle Time Without Flow Control The ATA Flash Disk Controller’s minimum cycle time is 120 ns. 11.2.1.6.25 Word 68: Minimum PIO Transfer Cycle Time With IORDY The ATA Flash Disk Controller’s minimum cycle time is 120 ns, e.g., PIO Mode-4. 11.2.1.6.26 Word 80: Major Version Number If not 0000H or FFFFH, the device claims compliance with the major version(s) as indicated by bits (6:1) being set to one. Since ATA standards maintain downward compatibility, a device may set more than one bit. SST55LD019x supports ATA-1 to ATA-6. 11.2.1.6.27 Word 81: Minor Version Number If an implementer claims that the revision of the standard they used to guide their implementation does not need to be reported or if the implementation was based upon a standard prior to the ATA-3 standard, word 81 should be 0000H or FFFFH.

During the DMA transfer phase of a Read-DMA command, the ATA Flash Disk Controller will provide the status of the BSY bit or the DRQ bit until the command is completed. 11.2.1.13 Read-Multiple - C4H Bit -> 7 6 5 4 2 1 0 C4H Command (7) C/D/H (6) 3 1 LBA 1 Drive Head (LBA 27-24) Cyl High (5) Cylinder High (LBA 23-16) Cyl Low (4) Cylinder Low (LBA 15-8) Sec Num (3) Sector Number (LBA 7-0) Sec Cnt (2) Sector Count Feature (1) X Note: The current revision of the ATA Flash Disk Controller can support up to a block count of 1 as indicated in the Identify-Drive Command information. The Read-Multiple command is similar to the Read-Sector(s) command. Interrupts are not generated on every sector, but on the transfer of a block which contains the number of sectors defined by a Set Multiple command. Command execution is identical to the Read-Sectors operation except that the number of sectors defined by a Set Multiple command are transferred without intervening interrupts. DRQ qualification of the transfer is required only at the start of the data block, not on each sector. The block count of sectors to be transferred without intervening interrupts is programmed by the SetMultiple-Mode command, which must be executed prior to the Read-Multiple command. When the Read-Multiple command is issued, the Sector Count register contains the number of sectors (not the number of blocks or the block count) requested. If the number of requested sectors is not evenly divisible by the block count, as many full blocks as possible are transferred, followed by a final, partial block transfer. The partial block transfer is for n sectors, where n = remainder (sector count/block count). If the Read-Multiple command is attempted before the Set-Multiple-Mode command has been executed or when Read-Multiple commands are disabled, the Read-Multiple operation is rejected with an ©2006 Silicon Storage Technology, Inc. S71241-04-000 38 12/06 ATA Flash Disk Controller SST55LD019A / SST55LD019B / SST55LD019C Data Sheet Aborted Command error. Disk errors encountered during Read-Multiple commands are posted at the beginning of the block or partial block transfer, but DRQ is still set and the data transfer will take place as it normally would, including transfer of corrupted data, if any. Interrupts are generated when DRQ is set at the beginning of each block or partial block. The error reporting is the same as that on a Read-Sector(s) command. 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. At command completion, the Command Block registers contain the cylinder, head and sector number of the last sector read. If an error occurs, the read terminates at the sector where the error occurred. The Command Block registers contain the cylinder, head and sector number of the sector where the error occurred. The flawed data is pending in the sector buffer. Subsequent blocks or partial blocks are transferred only if the error was a correctable data error. All other errors cause the command to stop after transfer of the block which contained the error. 11.2.1.14 Read-Long-Sector - 22H or 23H Bit -> 7 6 5 4 Command (7) C/D/H (6) Cyl High (5) 3 2 1 0 22H or 23H 1 LBA 1 Drive Head (LBA 27-24) Cylinder High (LBA 23-16) Cyl Low (4) Cylinder Low (LBA 15-8) Sec Num (3) Sector Number (LBA 7-0) Sec Cnt (2) X Feature (1) X The Read-Long-Sector command performs similarly to the Read-Sector(s) command except that it returns 516 Bytes of data instead of 512 Bytes. During a Read-Long-Sector command, the ATA Flash Disk Controller does not check the ECC bytes to determine if there has been a data error. Only singlesector Read-Long-Sector operations are supported. The transfer consists of 512 Bytes of data transferred in Word-Mode followed by 4 Bytes of ECC data transferred in Byte-Mode. This command has the same protocol as the Read-Sector(s) command. Use of this command is not recommended. ©2006 Silicon Storage Technology, Inc.

A sector count of 0 requests 256 sectors. The transfer begins at the sector specified in the Sector Number register. When this command is issued and after each sector of data (except the last one) has been read by the host, the ATA Flash Disk Controller sets BSY, puts the sector of data in the buffer, sets DRQ, clears BSY, and generates an interrupt. The host then reads the 512 Bytes of data from the buffer. ©2006 Silicon Storage Technology, Inc.

When the command is accepted, the ATA Flash Disk Controller sets BSY. When the requested sectors have been verified, the ATA Flash Disk Controller clears BSY and generates an interrupt. Upon command completion, the Command Block registers contain the cylinder, head, and sector number of the last sector verified. If an error occurs, the verify terminates at the sector where the error occurs. The Command Block registers contain the cylinder, head and sector number of the sector where the error occurred.

If the identifier bit is set to user, then the device compares the supplied password with the stored User password. If the password compare fails, the device returns “command aborted” to the host and decrements the unlock counter. This counter is initially set to five and is decremented for each password mismatch when Security-Unlock is issued and the device is locked. Once this counter reaches zero, the Security-Unlock and SecurityErase-Unit commands are command aborted until after a Power-on reset or a hardware reset is received. Security-Unlock commands issued when the device is unlocked have no effect on the unlock counter. 11.2.1.26 Seek - 7XH Bit -> 7 6 5 4 C/D/H (6) 3 2 1 0 7XH Command (7) 1 LBA 1 Drive Head (LBA 27-24) Cyl High (5) Cylinder High (LBA 23-16) Cyl Low (4) Cylinder Low (LBA 15-8) Sec Num (3) X (LBA 7-0) Sec Cnt (2) X Feature (1) X This command is effectively a no operation, although it does perform a range check of cylinder and head or LBA address and returns an error if the address is out of range. ©2006 Silicon Storage Technology, Inc.

S71241-04-000 47 12/06 ATA Flash Disk Controller SST55LD019A / SST55LD019B / SST55LD019C Data Sheet Features 01H and 81H are used to enable and clear 8-bit data transfer mode. If the 01H feature command is issued all data transfers will occur on the low order D7-D0 data bus and the IOCS16# signal will not be asserted for data register accesses. Features 02H and 82H allow the host to enable or disable write cache in the ATA Flash Disk Controllers that implement write cache. When the subcommand Disable-Write-Cache is issued, the ATA Flash Disk Controller should initiate the sequence to flush cache to non-volatile memory before command completion. Feature 03H allows the host to select the transfer mode by specifying a value in the Sector Count register. The upper 5 bits define the type of transfer and the low order 3 bits encode the mode value. One PIO mode is selected at all times. The host may change the selected modes by the Set-Features command. Feature 05H allows the host to enable advanced power management. To enable advanced power management, the host writes the Sector Count register with the desired advanced power management level and then executes a Set-Features command with subcommand code 05H. The power management level is a scale from the lowest power consumption setting of 01H to the maximum performance level of FEH. Table 11-10 shows these values. TABLE11-10:Advanced Power Management Levels Level Sector Count Value Maximum performance FEH Intermediate power management levels without standby Minimum power consumption without standby 81H-FDH 80H Intermediate power management levels with standby 02H-7FH Minimum power consumption with standby 01H Reserved FFH Reserved 00H T11-10.0 1241 ©2006 Silicon Storage Technology, Inc. S71241-04-000 48 12/06 ATA Flash Disk Controller SST55LD019A / SST55LD019B / SST55LD019C Data Sheet Device performance may increase with increasing power management levels. Device power consumption may increase with increasing power management levels. The power management levels may contain discrete bands. For example, a ATA Flash Disk Controller may implement one power management method from 80H to A0H and a higher performance, higher power consumption method from level A1H to FEH. Feature 85H disables Advanced Power Management. Subcommand 85H may not be implemented on all devices that implement Set Features subcommand 05H. Features 0AH and 8AH are used to enable and disable Power Level 1 commands. Feature 0AH is the default feature for the ATA Flash Disk Controller with extended power. Features 55H and BBH are the default features for the ATA Flash Disk Controller; thus, the host does not have to issue this command with these features unless it is necessary for compatibility reasons. Feature code 9AH enables the host to configure the device to best meet the host system’s power requirements. The host sets a value in the Sector Count register that is equal to one-fourth of the desired maximum average current (in mA) that the device should consume. For example, if the Sector Count register is set to 6, the device would be configured to provide the best possible performance without exceeding 24 mA. Upon completion of the command, the device responds to the host with the range of values supported by the device. The minimum value is set in the Cylinder Low register, and the maximum value is set in the Cylinder High register. The default value, after a power on reset, is to operate at the highest performance and therefore the highest current mode. The device will accept values outside this programmable range, but will operate either at the lowest power or highest performance as appropriate. Features 66H and CCH can be used to enable and disable whether the Power-on Reset (POR) Defaults will be set when a software reset occurs.

This command is similar to the Write-Sectors command. The ATA Flash Disk Controller sets BSY within 400 ns of accepting the 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 execution is identical to the Write-Sectors operation except that the number of sectors defined by the Set Multiple command is transferred without intervening interrupts. DRQ qualification of the transfer is required only at the start of the data block, not on each sector. The block count of sectors to be transferred without intervening interrupts is programmed by the SetMultiple-Mode command, which must be executed prior to the Write-Multiple command. When the Write-Multiple command is issued, the Sector Count register contains the number of sectors (not the number of blocks or the block count) requested. If the number of requested sectors is not evenly divisible by the sector/block, as many full blocks as possible are transferred, followed by a final, partial block transfer. The partial block transfer is for n sectors, where: n = remainder (sector count/block). If the Write-Multiple command is attempted before the Set-Multiple-Mode command has been executed or when Write-Multiple commands are disabled, the Write-Multiple operation will be rejected with an aborted command error. Errors encountered during Write-Multiple commands are posted after the attempted writes of the block or partial block transferred. The Write command ends with the sector in error, even if it is in the middle of a block. Subsequent blocks are not transferred in the event of an error. Interrupts are generated when DRQ is set at the beginning of each block or partial block. The Command Block registers contain the cylinder, head and sector number of the sector where the error occurred and the Sector Count register contains the residual number of sectors that need to be transferred for successful completion of the command e.g. each block has 4 sectors, a request for 8 sectors is issued and an error occurs on the third sector. The Sector Count register contains 6 and the address is that of the third sector. ©2006 Silicon Storage Technology, Inc.

When this command is accepted, the ATA Flash Disk Controller sets BSY, then sets DRQ and clears BSY, then waits for the host to fill the sector buffer with the data to be written. No interrupt is generated to start the first host transfer operation. No data should be transferred by the host until BSY has been cleared by the host. For multiple sectors, after the first sector of data is in the buffer, BSY will be set and DRQ will be cleared. After the next buffer is ready for data, BSY is cleared, DRQ is set and an interrupt is generated. When the final sector of data is transferred, BSY is set and DRQ is cleared. It will remain in this state until the command is completed at which time BSY is cleared and an interrupt is generated. If an error occurs during a write of more than one sector, writing terminates at the sector where the error occurs. The Command Block registers contain the cylinder, head and sector number of the sector where the error occurred. The host may then read the command block to determine what error has occurred, and on which sector. ©2006 Silicon Storage Technology, Inc.
