Power Management
7-10
Note
If the debug logic is included in a powered-down domain, then nTDOEN needs to be
handled carefully. It cannot be clamped to 0 because this enables it during power down.
Either:
•
Insert inverters either side of the clamp.
•
Ensure that the external system masks nTDOEN when the core is powered down.
•
Clamp nTDOEN to 1 during power down.
