Figure 10 shows how to insert or remove the

xD-Picture Card
card to prevent electrostatic discharge damage to the card and to keep any moisture or
other contaminants off the contacts. Do not remove or insert the
being accessed.
It is possible to hot-swap xD-Picture Cards without removing power from the RCM3365/
RCM3375 module. The file system must be closed before the cards can be hot-swapped.
The chip selects associated with the NAND flash and the xD-Picture Card must be set to
their inactive state, and read/write operations addressed to the NAND flash area cannot be
allowed to occur. These operations can be initiated in software by sensing an external
switch actuated by the user, and the xD-Picture Card can then be removed and replaced
with a different one. Once the application program detects a new card, the file system can
be opened. These steps allow the xD-Picture Card to be installed or removed without
affecting either the program, which continues to run on the RCM3365/RCM3375 module,
or the data stored on the xD-Picture Card.
The FAT_HOT_SWAP_336x0.C sample program in the SAMPLES\FileSystem\
folder illustrates this hot-swapping procedure.
Rabbit recommends that you use header J6 only for the
devices are not supported. Be careful to remove and insert the
and be careful not to insert any foreign objects, which may short out the contacts and lead
to the destruction of your
Sample programs in the SAMPLES\RCM3360\NANDFlash folder illustrate the use of
the NAND flash. These sample programs are described in Section 3.2.1, "Use of NAND
Flash." Pay careful attention to the sample programs to see how to close files and secure
any data on the
