4.4 SAM and PIC32C Arm Devices - On-Chip Debugging
Both SAM and PIC32C microcontrollers are based on Arm® Cortex-M® core. Debug features available depend on the type of core (see table below). Debug connectors support SWO and JTAG.
For more information on which devices have which cores, see 32-bit PIC® and SAM Microcontrollers or your device data sheet. See also CoreSight documentation provided by Arm.
| Cortex-M Types | Debug Support |
|---|---|
| Cortex-M0+ | Debug Optional: Basic debug functionality includes processor halt, single-step, processor core register access, Reset and HardFault Vector Catch, unlimited software breakpoints, and full system memory access. Also 1/2/3/4 breakpoint, and 1/2 watchpoint functionality. |
| Cortex-M23 | Debug Optional: Basic debug functionality includes processor halt, single-step, processor core register access, reset and HardFault Vector Catch, unlimited software breakpoints, and full system memory access. Also 1/2/3/4 breakpoint, and 1/2/3/4 watchpoint functionality. |
| Cortex-M4, M4F | Debug Optional: Basic debug functionality includes processor halt, single-step, processor core register access, Vector Catch, unlimited software breakpoints, and full system memory access. Also various breakpoint and 1/4 watchpoint functionality. |
| Cortex-M7 | Cortex-M7 debug functionality includes processor halt, single-step, processor core register access, Vector Catch, unlimited software breakpoints, and full system memory access. The processor also includes support for 4/8 hardware breakpoints and 2/4 watchpoints configured during implementation. |
