CompactFlash Support (EBI0 only)
I/O Mode, Common Memory Mode, Attribute Memory Mode and True IDE Mode
The External Bus Interface 0 integrates circuitry that interfaces to CompactFlash devices.
The CompactFlash logic is driven by the Static Memory Controller (SMC) on the NCS4 and/or
NCS5 address space. Programming the EBI0_CS4A and/or EBI0_CS5A bit of the EBI0_CSA
Register in the Chip Configuration User Interface to the appropriate value enables this logic. For
details on this register, refer to the in the Bus Matrix Section. Access to an external Compact-
Flash device is then made by accessing the address space reserved to NCS4 and/or NCS5 (i.e.,
between 0x5000 0000 and 0x5FFF FFFF for NCS4 and between 0x6000 0000 and 0x6FFF
FFFF for NCS5).
All CompactFlash modes (Attribute Memory, Common Memory, I/O and True IDE) are sup-
ported but the signals _IOIS16 (I/O and True IDE modes) and _ATA SEL (True IDE mode) are
not handled.
Within the NCS4 and/or NCS5 address space, the current transfer address is used to distinguish
I/O mode, common memory mode, attribute memory mode and True IDE mode.
The different modes are accessed through a specific memory mapping as illustrated on
21-4. A[23:21] bits of the transfer address are used to select the desired mode as described in
Table 21-6 on page
Figure 21-4. CompactFlash Memory Mapping
Note:
The A22 pin is used to drive the REG signal of the CompactFlash Device (except in True IDE
mode).
