TTS S22G G~~88G GC CFF226666 266X CompactFlash Card CF-ATA Registers The following section describes the hardware registers used by the host software to issue commands to the CompactFlash device. These registers are often collectively referred to as the “task file.” Data Register (Address - 1F0h[170h];Offset 0,8,9) The Data Register is a 16 bit register, and it is used to transfer data blocks between the CompactFlash Storage Card data buffer and the Host. This register overlaps the Error Register.
TTS S22G G~~88G GC CFF226666 266X CompactFlash Card Feature Register (Address - 1F1h[171h]; Offset 1, 0Dh Write Only) This register provides information regarding features of the CompactFlash Storage Card that the host can utilize. This register is also accessed in PC Card modes on data bits D15-D8 during a write operation to Offset 0 with -CE2 low and -CE1 high.
TTS S22G G~~88G GC CFF226666 266X CompactFlash Card Bit 3 (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. Bit 2 (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. Bit 1 (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.
TTS S22G G~~88G GC CFF226666 266X CompactFlash Card 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. This register can be written even if the device is BUSY. The bits are defined as follows: Bit 7: this bit is ignored by the CompactFlash Storage Card. The host software should set this bit to 0. Bit 6: this bit is ignored by the CompactFlash Storage Card.
