	  Indicates that the workaround for the anomaly 160 that affects
	  the nRF5340 SoC should be applied.
	  This option is enabled by default for the Application MCU when
	  DC/DC mode is enabled for the VREGMAIN or VREGRADIO regulator
	  and always for the Network MCU.
	  If this option is enabled, but the workaround cannot be applied,
	  because the system clock is disabled, a related cmake warning is
	  issued.

	select ARM_ON_EXIT_CPU_IDLE
	help
	  Indicates that the workaround for the anomaly 168 that affects
	  the nRF5340 SoC should be applied.
	  The workaround involves execution of 8 NOP instructions when the CPU
	  exist its idle state (when the WFI/WFE instruction returns) and it is
	  enabled by default for both the application and network core.

	help
	  Indicates that the anomaly 168 workaround is to be extended to cover
	  also a specific case when the WFI/WFE instruction is executed at 128
	  MHz from RAM. Then, 26 instead of 8 NOP instructions needs to be
	  executed after WFI/WFE. This extension is not enabled by default.

	  Indicates that the pre-tick workaround for the anomaly 165 that affects
	  the nRF5340 SoC should be applied. The workaround applies to wake ups caused
	  by EVENTS_COMPARE and EVENTS_OVRFLW on RTC0 and RTC1 for which interrupts are
	  enabled through INTENSET register. The case when these events are generated
	  by EVTEN but without interrupts enabled through INTENSET is not handled.
	  The EVENTS_TICK event is not handled.
