Determining the core and system state
When the core is in debug state, you can examine the core and system state by forcing
the load and store multiples into the instruction pipeline.
Before you can examine the core and system state, the debugger must determine
whether the processor entered debug from Thumb state or ARM state, by examining
bit 4 of the EmbeddedICE Logic debug status register. When bit 4 is HIGH, the core has
entered debug from Thumb state.
For more details about determining the core state, see Determining the core and system
state on page B-24.
