Wait For Interrupt is a hint instruction that permits the processor to enter a low-power state until one of a number of asynchronous events occurs. For more information, see Wait For Interrupt on page B1-1202. In an implementation that includes the Virtualization Extensions, if HCR.TWI is set to 1, execution of a WFI instruction in a Non-secure mode other than Hyp mode generates a Hyp Trap exception if, ignoring the value of the HCR.TWI bit, conditions permit the processor to suspend execution. For more information see Trapping use of the WFI and WFE instructions on page B1-1255.
