Disabling EmbeddedICE-RT
You can disable EmbeddedICE-RT by wiring the DBGEN input LOW.
When DBGEN is LOW:
•
•
•
DBGIEBKPT, DBGDEWPT, and DBGRQ are forced LOW to the core.
(DBGRQ is the internal DBGRQ, which is a combination of the external input
EDBGRQ and the debug control register bit 1 DBGRQ.)
DBGACK is forced LOW from the ARM9E-S.
Interrupts pass through to the processor uninhibited.
