27.6
dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/50X,
and PIC24EPXXXGP/MC20X devices implement a
JTAG interface, which supports boundary scan device
testing. Detailed information on this interface is
provided in future revisions of the document.
27.7
The dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/
50X, and PIC24EPXXXGP/MC20X 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 device just before shipping the
product. Serial programming also allows the most recent
firmware or a custom firmware to be programmed. Refer
to
Specification for Devices with Volatile Configuration Bits”
(DS70663)
Programming (ICSP).
Any of the three pairs of programming clock/data pins
can be used:
• PGEC1 and PGED1
• PGEC2 and PGED2
• PGEC3 and PGED3

When MPLAB
debugger, the in-circuit debugging functionality is
enabled. This function allows simple debugging func-
tions when used with MPLAB IDE. Debugging function-
ality is controlled through the PGECx (Emulation/
Debug Clock) and PGEDx (Emulation/Debug Data) pin
functions.
Any of the three pairs of debugging clock/data pins can
be used:
• PGEC1 and PGED1
• PGEC2 and PGED2
• PGEC3 and PGED3
To use the in-circuit debugger function of the device,
the design must implement ICSP connections to
MCLR, V
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 (PGECx and PGEDx).
27.9
The dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/
50X, and PIC24EPXXXGP/MC20X devices offer basic
implementation of CodeGuard Security that supports
only General Segment (GS) security. This feature helps
protect individual Intellectual Property.
