Introduction CHAPTER 1 1.1 General Description SanDisk CompactFlash® Memory Card products provide high capacity solid-state flash memory that electrically complies with the Personal Computer Memory Card International Association ATA (PC Card ATA) standard. (In Japan, the applicable standards group is JEIDA.) The CompactFlash Memory Card Series also supports a True IDE Mode that is electrically compatible with an IDE disk drive.

Introduction 1.7.1 SanDisk CompactFlash Card OEM Product Manual Technology Independence The 512-byte sector size of the CompactFlash Memory Card is the same as that in an IDE magnetic disk drive. To write or read a sector (or multiple sectors), the host computer software simply issues a Read or Write command to the card. This command contains the address and the number of sectors to write/read. The host software then waits for the command to complete.
PAGE 11
SanDisk CompactFlash Card OEM Product Manual 1.7.5 Introduction Automatic Sleep Mode A unique feature of the SanDisk CompactFlash Memory Card is automatic entrance and exit from sleep mode. Upon completion of a command, the card will enter sleep mode to conserve power if no further commands are received within 5 msec. The host does not have to take any action for this to occur. In most systems, the CompactFlash Memory Card is in sleep mode except when the host is accessing it, thus conserving power.

SanDisk CompactFlash Card OEM Product Manual ATA Command Description A host can choose the transfer mechanism by Set Transfer Mode and 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.
PAGE 76
ATA Command Description SanDisk CompactFlash Card OEM Product Manual If the Sector Count Register contains a valid value and the block count is supported, the value is loaded for all subsequent Read Multiple and Write Multiple commands and execution of those commands is enabled. If a block count is not supported, an Aborted Command error is posted, and Read Multiple and Write Multiple commands are disabled.

SanDisk CompactFlash Card OEM Product Manual 5.1.21 ATA Command Description Standby–96H, E2H 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. Recovery from sleep mode is accomplished by simply issuing another command (reset is not required). Table 5-30 Standby Bit 7 6 5 Command (7) 3 2 1 0 E2H or 96H C/D/H (6) 5.1.

SanDisk CompactFlash Card OEM Product Manual 5.1.26 ATA Command Description Write DMA Command–CAH, CBH The Write DMA command in Table 5 33 executes in a similar manner to WRITE SECTOR(S) except for the following: • The host initialised the DMA channel prior to issuing the command. • Data transfers are qualified by DMARQ and are performed by the DMA channel. • The device issues only one interrupt per command to indicate that data transfer has termi nated and status is available.
PAGE 80
ATA Command Description SanDisk CompactFlash Card OEM Product Manual 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 Set Multiple Mode command, which must be executed prior to the Write Multiple command.

SanDisk CompactFlash Card OEM Product Manual 5.1.29 ATA Command Description Write Multiple without Erase–CDH SanDisk does not recommend the use of this command in new designs but it is supported as a normal Write Sectors command for backward compatibility reasons.
