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