__STATIC_INLINE void | EMU_IntClear (uint32_t flags) |
Clear one or more pending EMU interrupts. More... | |
__STATIC_INLINE void | EMU_IntDisable (uint32_t flags) |
Disable one or more EMU interrupts. More... | |
__STATIC_INLINE void | EMU_IntEnable (uint32_t flags) |

__STATIC_INLINE void | EMU_IntSet (uint32_t flags) |
Set one or more pending EMU interrupts. More... | |
__STATIC_INLINE void | EMU_Lock (void) |
Lock the EMU in order to protect its registers against unintended modification. More... | |
__STATIC_INLINE void | EMU_Unlock (void) |
Unlock the EMU so that writing to locked registers again is possible. | |
__STATIC_INLINE void | EMU_PowerLock (void) |
Lock the EMU regulator control registers in order to protect against unintended modification. | |
__STATIC_INLINE void | EMU_PowerUnlock (void) |
Unlock the EMU power control registers so that writing to locked registers again is possible. | |
__STATIC_INLINE void | EMU_EM2Block (void) |
Block entering EM2 or higher number energy modes. | |
__STATIC_INLINE void | EMU_EM2UnBlock (void) |
Unblock entering EM2 or higher number energy modes. | |
__STATIC_INLINE void | EMU_UnlatchPinRetention (void) |
When EM4 pin retention is set to emuPinRetentionLatch, then pins are retained through EM4 entry and wakeup. The pin state is released by calling this function. The feature allows peripherals or GPIO to be re-initialized after EM4 exit (reset), and when the initialization is done, this function can release pins and return control to the peripherals or GPIO. | |
