HLT

Halt instruction. An HLT instruction can generate a Halt Instruction debug event, which causes entry into Debug state.

Within a guarded memory region, while PSTATE.BTYPE != 0b00, a HLT instruction that would cause entry into Debug state will not generate a Branch Target Exception and will cause entry into Debug state as normal. For more information, see PSTATE.BTYPE.
