4.5.10 Compatibility
mDOC H1 requires TrueFFS driver 6.3.0 or higher. Since this driver does not support some of
mDOC products, migrating from other than mDOC H1 to mDOC H1 requires changing the
TrueFFS driver.
When using different drivers (e.g. TrueFFS SDK, BootSDK, Windows Mobile, etc.) to access
mDOC H1, verify that all software is based on the same code base version. It is also important to
use only tools (e.g. DFORMAT, DINFO, DIMAGE, etc.) from the same version as the TrueFFS
drivers used in the application. Failure to do so may lead to unexpected results, such as lost or
corrupted data. The driver version can be verified by the sign-on messages displayed, or by the
version information presented by the driver or tool.

TrueFFS utilizes an 8KB memory window in the CPU address space, consisting of four 2KB
sections as depicted in Figure 8. When in Reset mode, read cycles from sections 1 and 2 always
return the value 00H to create a fixed and known checksum. When in Normal mode, these two
sections are used for the internal registers. The 1KB Programmable Boot Block is in section 0 and
section 3, to support systems that search for a checksum at the boot stage both from the top and
bottom of memory. The 1KB Programmable Boot Block is aliased two times in both section 0 and
section 3 for redundancy reasons. The addresses described here are relative to the absolute starting
address of the 8KB memory window.
