3.1.3 Memory Mapped Addressing
When the CompactFlash card registers are accessed via memory references, the registers appear in the common
memory space window: 0-2 KByte as follows:

1. Register 0 is accessed with -CE1 low and -CE2 low 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 second byte
accessed is the Odd Byte of the equivalent word access.
A byte access to address 0 with -CE1 high and -CE2 low accesses the error (read) or feature (write) register.
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.

3. Accesses to even addresses between 400H and 7FFH access register 8. Accesses to odd addresses between 400H and 7FFH
access register 9. This 1 KByte memory window to the data register is provided so that hosts can perform memory to memory block
moves to the data register when the register lies in memory space.
Some hosts, such as the X86 processors, must increment both the source and destination addresses when executing the memory to
memory block move instruction. Some PCMCIA socket adapters also have auto incrementing address logic embedded within them.
This address window allows these hosts and adapters to function efficiently.
Note that this entire window accesses the Data Register FIFO and does not allow random access to the data buffer within the Com-
pactFlash card.
A word access to address at offset 8 will provide even data on the low-order byte of the data bus, along with odd data at offset 9 on
the high-order byte of the data bus.
