PIC24HJ32GP202/204 and PIC24HJ16GP304
18.5
PIC24HJ32GP202/204
devices implement a JTAG interface, which supports
boundary scan device testing, as well as in-circuit pro-
gramming. Detailed information on this interface will be
provided in future revisions of the document.
18.6
The PIC24HJ32GP202/204 and PIC24HJ16GP304
product families offer the intermediate implementation
of CodeGuard Security. CodeGuard Security allows
multiple parties to securely share resources (memory,

feature helps to 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 the single chip.
The code protection features are controlled by the
Configuration registers: FBS and FGS. The Secure
segment and RAM is not implemented.
