SanDisk CompactFlash Memory cards can be configured as a high performance
I/O device in the following ways:
Communication to or from the card uses 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. Table 30 describes these methods in detail.

Register 0 is accessed with -CE1 low and -CE2 low (and A0 = Do not care) as a
word register on the combined Odd Data Bus and Even Data Bus (D15-D0). 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
