TS2G~8GCF266		266X CompactFlash Card

CF-ATA Drive Register Set Definition and Protocol

The CompactFlash Storage Card can be configured as a high performance I/O device through:

a)The standard PC-AT disk I/O address spaces 1F0h-1F7h, 3F6h-3F7h (primary) or 170h- 177h, 376h-377h (secondary) with IRQ 14 (or other available IRQ).

b)Any system decoded 16 byte I/O block using any available IRQ.

c)Memory space.

The communication to or from the CompactFlash Storage Card is done using the Task File registers, which provide all the necessary registers for control and status information related to the storage medium. The PCMCIA interface connects peripherals to the host using four register mapping methods. Table 39 is a detailed description of these methods:
