DBGPWRDUP debug signal

You must set the DBGPWRDUP signal LOW before removing power to the processor domain. After power is restored to the processor 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 processor and SCU power domains.
