| 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 |

| Indicates that the workaround for the anomaly 168 that affects |
| the nRF5340 SoC should be applied. |

| 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. |

| 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. |
