24.8
The
dsPIC33FJ64GS406/606/608/610 devices offer the
intermediate implementation of CodeGuard™ Security.
CodeGuard Security enables multiple parties to securely
share resources (memory, interrupts and peripherals) on
a single chip. This feature helps protect individual
Intellectual Property in collaborative system designs.

When coupled with software encryption libraries,
CodeGuard™ Security can be used to securely update
Flash even when multiple IPs reside on a single chip.
The code protection features are controlled by the
Configuration registers: FBS and FGS.
Secure segment and RAM protection is not implemented
in
dsPIC33FJ64GS406/606/608/610 devices.
