3.0 SOFTWARE INTERFACE
3.1 CF-ATA Drive Register Set Definition and Protocol
The CompactFlash card can be configured as a high performance I/O device through:
1. Standard PC-AT disk I/O address spaces 1F0H-1F7H, 3F6H-3F7H (primary);
170H-177H, 376H-377H (secondary) with IRQ 14 (or other available IRQ).
2. Any system decoded 16 Byte I/O block using any available IRQ.
3. Memory space.
The communication to or from the CompactFlash card is done using the Task File registers which provide all the
necessary registers for control and status information. The PCMCIA interface connects peripherals to the host
using four register mapping methods. The following is a detailed description of these methods:

1. Register 0 is accessed with -CE1 low and -CE2 low (and A
0
= Don’t Care) as a word register on the combined Odd Data Bus and
Even Data Bus (D
15
-D
0
). This register may also be accessed by a pair of byte accesses to the offset 0 with -CE1 low and -CE2 high.
Note that the address space of this word register overlaps the address space of the Error and Feature byte-wide registers which lie at
offset 1. When accessed twice as byte register with -CE1 low, the first byte to be accessed is the Even Byte of the word and the sec-
ond byte accessed is the Odd Byte of the equivalent word access.
2. A byte access to register 0 with -CE1 high and -CE2 low accesses the error (read) or feature (write) register.
