Product data sheet
7.18 Emulation and debugging
Debug functions are integrated into the ARM Cortex-M0. Serial wire debug functions are
supported in addition to a standard JTAG boundary scan. The ARM Cortex-M0 is
configured to support up to four breakpoints and two watch points.
The RESET pin selects between the JTAG boundary scan (RESET = LOW) and the ARM
SWD debug (RESET = HIGH). The ARM SWD debug port is disabled while the
LPC11U3x is in reset.
To perform boundary scan testing, follow these steps:
Remark: The JTAG interface cannot be used for debug purposes.
1. Erase any user code residing in flash.
2. Power up the part with the RESET pin pulled HIGH externally.
3. Wait for at least 250 μs.
4. Pull the RESET pin LOW externally.
5. Perform boundary scan operations.
6. Once the boundary scan operations are completed, assert the TRST pin to enable the
SWD debug mode, and release the RESET pin (pull HIGH).
