[. . . ] 3) The signal should be tied to VCC by the host. 4) The mode is required for CompactFlash Storage Cards. 5) The -CSEL signal is ignored by the card in PC Card modes. However, because it is not pulled upon the card in these modes, it should not be left floating by the host in PC Card modes. [. . . ] The bits are defined as follows: 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. Secondary address (377) or in an independently decoded Address Space when a Floppy Disk Controller is located at the Primary addresses. 2) Do not install a Floppy and a CompactFlash Storage Card in the system at the same time. 3) Implement a socket adapter that can be programmed to (conditionally) tri-state D7 of I/0 address 3F7h/377h when a CompactFlash Storage Card is installed and conversely to tristate D6-D0 of I/O address 3F7h/377h when a floppy controller is installed. 4) Do not use the CompactFlash Storage Card's Drive Address register. This may be accomplished by either a) If possible, program the host adapter to enable only I/O addresses 1F0h-1F7h, 3F6h (or 170h-177h, 176h) to the CompactFlash Storage Card or b) if provided use an additional Primary / Secondary configuration in the CompactFlash Storage Card which does not respond to accesses to I/O locations 3F7h and 377h. With either of these implementations, the host software shall not attempt to use information in the Drive Address Register. Bit 6 (-WTG): this bit is 0 when a write operation is in progress; otherwise, it is 1. Bit 5 (-HS3): this bit is the negation of bit 3 in the Drive/Head register. Transcend Information Inc. 42 V1. 7 TS32M~1GCF80 TS32M~1GCF80 Bit 4 (-HS2): this bit is the negation of bit 2 in the Drive/Head register. 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 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.

When Word 0 of the Identify drive information is 848Ah then the device is a CompactFlash Storage Card and complies with the CFA specification and CFA command set. It is recommended that PCMCIA modes of operation report only the 848Ah value as they are always intended as removable devices. [. . . ] Errors encountered during Write Multiple commands are posted after the attempted writes of theblock 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. [. . . ]
