Functions

NRF_STATIC_INLINE void nrf_regulators_dcdcen_set(NRF_REGULATORS_Type *p_reg, bool enable)¶

Function for enabling or disabling DCDC converter.

Parameters

p_reg – [in] Pointer to the structure of registers of the peripheral.
enable – [in] True if DCDC converter is to be enabled, false otherwise.

NRF_STATIC_INLINE void nrf_regulators_system_off(NRF_REGULATORS_Type *p_reg)¶

Function for putting CPU in system OFF mode.

This function puts the CPU into system off mode. The only way to wake up the CPU is by reset.

Note

This function never returns.

Parameters

p_reg – [in] Pointer to the structure of registers of the peripheral.

NRF_STATIC_INLINE nrf_regulators_mainregstatus_t nrf_regulators_mainregstatus_get(NRF_REGULATORS_Type const *p_reg)¶

Function for getting the main supply status.

Parameters

p_reg – [in] Pointer to the structure of registers of the peripheral.

Returns

The current main supply status.

NRF_STATIC_INLINE void nrf_regulators_pofcon_set(NRF_REGULATORS_Type *p_reg, bool enable, nrf_regulators_pof_thr_t thr)¶

Function for setting the power failure comparator configuration.
