While operating in Dual Partition mode, the dsPIC33CK512MPT608 family devices have the option
for both partitions to have their own defined security segments, as shown in Code Protection and CodeGuard™
Security. Alternatively, the
device can operate in Protected Dual Partition mode, where Partition 1 becomes
permanently erase/write-protected. Protected Dual Partition mode allows for a “Factory
Default” mode, which provides a fail-safe backup image to be stored in Partition 1.
dsPIC33CK512MPT608 family devices
can also operate in Privileged Dual Partition mode, where additional security
protections are implemented to allow for protection of intellectual property when
multiple parties have software within the device. In Privileged Dual Partition mode,
both partitions place additional restrictions on the FBSLIM register. These prevent
changes to the size of the Boot Segment and General Segment, ensuring that neither
segment will be altered.Figure 5-3. Relationship Between Partitions 1/2 and Active/Inactive Partitions
