DCPS3

Debug Change PE State to EL3, when executed in Debug state:

  • If executed at EL3 selects SP_EL3.
  • Otherwise, changes the current Exception level and SP to EL3 using SP_EL3.

The target exception level of a DCPS3 instruction is EL3.

On executing a DCPS3 instruction:

This instruction is undefined at all exception levels if either:

  • EDSCR.SDD == 1.
  • EL3 is not implemented.

This instruction is always undefined in Non-debug state.

For more information on the operation of the DCPSn instructions, see DCPS.
