dsPIC33FJ12GP201/202
18.5
The dsPIC33FJ12GP201/202 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.
18.6
The dsPIC33FJ12GP201/202 devices can be serially
programmed while in the end application circuit. This is
done with two lines for clock and data and three other
lines for power, ground and the programming
sequence. Serial programming allows customers to
manufacture boards with unprogrammed devices and
then program the digital signal controller just before
shipping the product. Serial programming also allows
the most recent firmware or a custom firmware to be
programmed.
Programming Specification (DS70152) for details
about In-Circuit Serial Programming (ICSP).
Any of the three pairs of programming clock/data pins
can be used:
• PGC1/EMUC1 and PGD1/EMUD1
• PGC2/EMUC2 and PGD2/EMUD2
• PGC3/EMUC3 and PGD3/EMUD3
18.7
When MPLAB
in-circuit debugging functionality is enabled. This
function allows simple debugging functions when used
with MPLAB IDE. Debugging functionality is controlled
through the EMUCx (Emulation/Debug Clock) and
EMUDx (Emulation/Debug Data) pin functions.
Any of the three pairs of debugging clock/data pins can
be used:
• PGC1/EMUC1 and PGD1/EMUD1
• PGC2/EMUC2 and PGD2/EMUD2
• PGC3/EMUC3 and PGD3/EMUD3
To use the in-circuit debugger function of the device,
the design must implement ICSP connections to
MCLR, V
pin pair. In addition, when the feature is enabled, some
of the resources are not available for general use.
These resources include the first 80 bytes of data RAM
and two I/O pins.

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