JTAG Interface

dsPIC33FJ32GS406/606/608/610

and

dsPIC33FJ64GS406/606/608/610 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.

In-Circuit Serial Programming

and

dsPIC33FJ64GS406/606/608/610

family

Digital

Signal Controllers (DSCs) 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. Refer to the “dsPIC33F/PIC24H Flash

Programming Specification” (DS70152) for details

about In-Circuit Serial Programming™ (ICSP™).

Any of the three pairs of programming clock/data pins

can be used:

• PGEC1 and PGED1

• PGEC2 and PGED2

• PGEC3 and PGED3

24.7

In-Circuit Debugger

When MPLAB ICD 3 is selected as a debugger, the 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:

• 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, VDD, VSS, PGECx, PGEDx and the EMUDx/

EMUCx 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.
