JTAG Interface
dsPIC33FJ32GP202/204 and dsPIC33FJ16GP304
devices implement a JTAG interface, which supports
boundary scan device testing, as well as in-circuit
programming. Detailed information on this interface will
be provided in future revisions of the document.

Code Protection and
CodeGuard™ Security
CodeGuard™ Security
The dsPIC33FJ32GP202/204 and
dsPIC33FJ16GP304 product families offer the
intermediate implementation of CodeGuard™ Security.
CodeGuard Security enables multiple parties to
securely share resources (memory, interrupts and
dsPIC33FJ16GP304 product families 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, Code-
Guard™ Security can be used to securely update Flash
even when multiple IPs reside on the single chip.
The code protection features are controlled by the
Configuration registers: FBS and FGS. The Secure
segment and RAM is not implemented.
