A4.9 Powering up the processor without system driven L2 flush

When powering down the processor, the PDMINERVA, PDL2, and PDCPU power domains are shut down and all state is lost.

To power up the processor, apply the following sequence:


  1. For each core in the cluster, assert nCPUPORESET LOW.
  2. Assert nL2RESET LOW and hold L2RSTDISABLE LOW.
  3. Apply power to the PDMINERVA and PDL2 domains while keeping the signals described in steps 1 and 2 LOW.
  4. Release the cluster output clamps.
  5. Continue a normal cold reset sequence.
