Debug Unit Cortex - R

Hi Experts,

What is the key advantage or any application notes on usage of Debug Unit. As I understand it specifies about how external debugger can interface it, but how it could be used by Software (Crash dump SW) within (embedded system) to control and debug issues without external debugger.

1. Can the Watchpoint and Breakpoint shall be set dynamically ?

2. When break point hits, can we re-route it to some Exception handler ?
