10.10.2 DBGPWRDUP debug signal

This section describes the DBGPWRDUP debug input signal.

DBGPWRDUP

You must set the DBGPWRDUP signal LOW before removing power to the core domain. After power is restored to the core domain, the DBGPWRDUP signal must be asserted HIGH. The EDPRSR.PU bit reflects the value of this DBGPWRDUP signal.

Note

DBGPWRDUP must be tied HIGH if the particular implementation does not support separate core and debug power domains.
