BRK

Breakpoint instruction. A BRK instruction generates a Breakpoint Instruction exception. The PE records the exception in ESR_ELx, using the EC value 0x3C, and captures the value of the immediate argument in ESR_ELx.ISS.

Within a guarded memory region, while PSTATE.BTYPE != 0b00, a BRK instruction will not generate a Branch Target Exception and will generate a Breakpoint Instruction exception as normal. For more information, see PSTATE.BTYPE.
