NRF_STATIC_INLINE bool nrf_power_dcdcen_vddh_get(NRF_POWER_Type const *p_reg)

Function for getting the state of DCDC converter on VDDH.

Parameters

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

Return values

  • true – Converter is enabled.

  • false – Converter is disabled.

NRF_STATIC_INLINE nrf_power_mainregstatus_t nrf_power_mainregstatus_get(NRF_POWER_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.
