3.3.4 SAM MCUs - JTAG/SWD Interfaces
SAM devices feature the Serial Wire Debug (SWD) interface for programming and debugging and/or
a JTAG interface with identical functionality. Check the device data sheet for supported interfaces of
that device.
3.3.4.1 JTAG Physical Interface
The JTAG interface consists of a four-wire Test Access Port (TAP) controller that is compliant with
the IEEE 1149.1 standard. The IEEE standard was developed to provide an industry-standard way
®
to efficiently test circuit board connectivity (Boundary Scan). Microchip AVR and SAM devices have
extended this functionality to include full Programming and On-chip Debugging support.
To use this target interface with MPLAB X IDE, open the Project Properties window, "ICD 5" category,
"Communications" option category, and select JTAG. For MIPS devices, select 2-wire or 4-wire JTAG.
Note: 2-wire JTAG uses standard ICSP pinout.
