Disabling EmbeddedICE
The EmbeddedICE Logic is disabled by setting DBGEN LOW.
Hard-wiring the DBGEN input LOW permanently disables the EmbeddedICE Logic.
However, you must not rely upon this for system security.
When DBGEN is LOW:
•
•
•
•
BREAKPT and DBGRQ are forced LOW to the core
DBGACK is forced LOW from the ARM7TDMI core
interrupts pass through to the processor uninhibited by the debug logic
EmbeddedICE Logic is put into a low-power mode.
