[. . . ] 6) If DMA operations are not used, the signal should be held high or tied to VCC by the host. For proper operation in older hosts: while DMA operations are not active, the card shall ignore this signal, including a floating condition 7) Signal usage in True IDE Mode except when Ultra DMA mode protocol is active. 8) Signal usage in True IDE Mode when Ultra DMA mode protocol DMA Write is active. 9) Signal usage in True IDE Mode when Ultra DMA mode protocol DMA Read is active. [. . . ] It is recommended that media access commands (such as Read Sectors and Write Sectors) that end with an error condition should have the address of the first sector in error in the command block registers. Transcend Information Inc. 51 V1. 2 Transcend IIndustriiall CF Card Transcend ndustr a CF Card (TS128M ~ 16GCF100II) (TS128M ~ 16GCF100 ) Device Control Register (Address - 3F6h[376h]; Offset Eh) This register is used to control the CompactFlash Storage Card interrupt request and to issue an ATA soft reset to the card. The bits are defined as follows: Bit 7: this bit is ignored by the CompactFlash Storage Card. Bit 2 (SW Rst): this bit is set to 1 in order to force the CompactFlash Storage Card to perform an AT Disk controller Soft Reset operation. This does not change the PCMCIA Card Configuration Registers as a hardware Reset does. The Card remains in Reset until this bit is reset to `0. ' Bit 1 (-IEn): the Interrupt Enable bit enables interrupts when the bit is 0. When the bit is 1, interrupts from the CompactFlash Storage Card are disabled. This bit also controls the Int bit in the Configuration and Status Register. Bit 0: this bit is ignored by the CompactFlash Storage Card. Transcend Information Inc. 52 V1. 2 Transcend IIndustriiall CF Card Transcend ndustr a CF Card (TS128M ~ 16GCF100II) (TS128M ~ 16GCF100 ) Card (Drive) Address Register (Address 3F7h[377h]; Offset Fh) This register is provided for compatibility with the AT disk drive interface. It is recommended that this register not be mapped into the host's I/O space because of potential conflicts on Bit 7. Bit 7: this bit is unknown. Implementation Note: Conflicts may occur on the host data bus when this bit is provided by a Floppy Disk Controller operating at the same addresses as the CompactFlash Storage Card. Following are some possible solutions to this problem for the PCMCIA implementation: 1) Locate the CompactFlash Storage Card at a non-conflicting address, i. e. To remain host backward compatible, the CompactFlash Storage Card expects a sector buffer of data from the host to follow the command with the same protocol as the Write Sector(s) command although the information in the buffer is not used by the CompactFlash Storage Card. If LBA=1 then the number of sectors to format is taken from the Sec Cnt register (0=256). The use of this command is not recommended.

The parameter words in the buffer have the arrangement and meanings defined in Table as below. Hosts should not depend on Obsolete words in Identify Device containing 0. Table 47 specifies each field in the data returned by the Identify Device Command. In Table as below, X indicates a numeric nibble value specific to the card and aaaa indicates an ASCII string specific to the particular drive.
