CompactFlash Support
I/O Mode, Common Memory Mode, Attribute Memory Mode and True IDE Mode
The External Bus Interface integrates circuitry that interfaces to CompactFlash devices.
The CompactFlash logic is driven by the SMC on the NCS[4] and/or NCS[5] address space.
Writing to the HMATRIX.SFR6.CS4A and/or HMATRIX.SFR6.CS5A bits the appropriate value
enables this logic. Access to an external CompactFlash device is then made by accessing the
address space reserved to NCS[4] and/or NCS[5].
All CompactFlash modes (Attribute Memory, Common Memory, I/O and True IDE) are sup-
ported but the signals _IOWR, _IOIS16 (I/O and True IDE modes) and _ATA SEL (True IDE
mode) are not handled.
Within the NCS[4] and/or NCS[5] address space, the current transfer address is used to distin-
guish 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
14-2 on page
as described in
Figure 14-2. CompactFlash Memory Mapping

Table 14-4.
CF Address Space
The ADDR[22] I/O line is used to drive the REG signal of the CompactFlash Device (except in
True IDE mode).
