dsPIC33FJXXXMCX06/X08/X10 Motor Control Family
devices implement a JTAG interface, which supports
boundary scan device testing, as well as in-circuit pro-
gramming. Detailed information on the interface will be
provided in future revisions of the document.
22.6
The dsPIC33F product families offer the advanced
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 IP are resident on the single chip.
The code protection features vary depending on the
actual dsPIC33F implemented. The following sections
provide an overview of these features.
The code protection features are controlled by the
Configuration registers: FBS, FSS and FGS.

simply done with two lines for clock and data and three
other lines for power, ground and the programming
sequence. This allows customers to manufacture
boards with unprogrammed devices and then program
the digital signal controller just before shipping the
product. This also allows the most recent firmware or a
custom firmware, to be programmed. Please refer to
the “dsPIC33F Flash Programming Specification”
(DS70152) document for details about ICSP.
Any 1 out of 3 pairs of programming clock/data pins
may be used:
• PGC1/EMUC1 and PGD1/EMUD1
• PGC2/EMUC2 and PGD2/EMUD2
• PGC3/EMUC3 and PGD3/EMUD3

When MPLAB
in-circuit debugging functionality is enabled. This func-
tion 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 1 out of 3 pairs of debugging clock/data pins may
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.
