Contiguous I/O Mapped
Addressing
When the system decodes a contiguous block of I/O
registers to select the CompactFlash Memory
Card, the registers are accessed in the block of I/O
space decoded by the system as follows:

Notes:
1. Register 0 is accessed with -CE1 low and -CE2 low (and A0 = 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
second 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. 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 than 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 supported. 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. Address lines which are not indicated are ignored by the CompactFlash Memory Card for accessing all the
registers in this table.
