DCPS2

Debug Change PE State to EL2.

Syntax

DCPS2 {#imm}

Where:

imm

Is an optional 16-bit unsigned immediate, in the range 0 to 65535, defaulting to 0.

Usage

Debug Change PE State to EL2 allows the debugger to move the PE into EL2 from a lower Exception Level or to a specific mode at the current Exception Level.

If the PE is at EL2 or lower, then the PE enters EL2h.

If the PE is at an Exception Level higher than EL2, then the PE does not change Exception Level but selects use of the stack pointer for the current Exception Level by updating PSTATE.SP.

This instruction is always UNDEFINED in Non-debug state.

For more information on the operation of this instructions, see DCPS in the ARMv8-A Architecture Reference Manual.
