lpc43xx JTAG Scan Chain

Debug and trace functions is integrated into the ARM cortex-m4.

Serial wire Debug and trace functions is supported in addition to a standard JTAG debug and parallel trace functions.

The ARM CORTEX-M4 is configured-to-eight breakpoints and four watch points.

The ARM cortex-m0 coprocessor supports JTAG Debug.

A Standard ARM Cortex-compliant debugger can debug the arm cortex-m4 and the arm cortex-m0 cores separately or both cores Simultaneously.

Remark:

In order to debug the ARM cortex-m0, release the M0 reset by software in the RGU block.
