3.1.2 Contiguous I/O Mapped Addressing
When the system decodes a contiguous block of I/O registers to select the CompactFlash card, the registers are
accessed in the block of I/O space decoded by the system as follows:
Note:
Address lines which are not indicated are ignored by the CompactFlash card for accessing all the registers in this table.

Notes

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 (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 address space of the Error and Feature byte-wide registers that 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. A byte access to register 0 with -CE1 high and -CE2 low accesses
the error (read) or feature (write) register.
2
2. Registers at offset 8, 9, and D are non-overlapping duplicates of the registers at offset 0 and 1.
Register 8 is equivalent to register 0, while register 9 accesses the Odd Byte. Therefore, if the registers are byte accessed in the
order 9 then 8 the data will be transferred Odd Byte then Even Byte.
Repeated byte accesses to register 8 or 0 will access consecutive (Even then Odd) Bytes from the data buffer. Repeated word
accesses to register 8, 9, or 0 will access consecutive words from the data buffer. Repeated byte accesses to register 9 are not sup-
ported. However, repeated alternating byte accesses to registers 8 then 9 will access consecutive (Even then Odd) Bytes from the
data buffer. Byte accesses to register 9 access only the Odd Byte of the data.
