High-Performance, 16-bit Digital Signal Controllers

Microchip Technology 

dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04

21.5 JTAG Interface

dsPIC33FJ06GS101/X02

and

dsPIC33FJ16GSX02/X04 devices implement a JTAG

interface, which supports boundary scan device test-

ing, as well as in-circuit programming. Detailed infor-

mation on this interface will be provided in future

revisions of the document.

21.6 In-Circuit Serial Programming

dsPIC33FJ06GS101/X02

and

dsPIC33FJ16GSX02/X04 family digital signal

controllers 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

21.7 In-Circuit Debugger

When MPLAB® ICD 2 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, and the PGECx/PGEDx 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.
