Function Documentation

__STATIC_INLINE void nrf_nvmc_erase_all_start ( NRF_NVMC_Type * p_reg )

Function for starting the erase of the whole NVM, including UICR.

This function purges all user code.

Parameters

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

__STATIC_INLINE void nrf_nvmc_icache_config_set	(	NRF_NVMC_Type *	p_reg,
		nrf_nvmc_icache_config_t	config
	)

Function for applying the Instruction Cache (ICache) configuration.

Enabling the cache can increase CPU performance and reduce power consumption by reducing the number of wait cycles and the number of flash accesses.

Parameters

[in]	p_reg	Pointer to the structure of registers of the peripheral.
[in]	config	ICache configuration.

__STATIC_INLINE bool nrf_nvmc_icache_enable_check ( NRF_NVMC_Type const * p_reg )

Function for checking if ICache is enabled.

Parameters

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

Return values

true	ICache enabled.
false	ICache disabled.

__STATIC_INLINE uint32_t nrf_nvmc_icache_hit_get ( NRF_NVMC_Type const * p_reg )

Function for getting the number of ICache hits.

Parameters

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

Return values

Number of the ICache hits.

__STATIC_INLINE void nrf_nvmc_icache_hit_miss_reset ( NRF_NVMC_Type * p_reg )

Function for resetting the ICache hit and miss counters.

Parameters

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

__STATIC_INLINE uint32_t nrf_nvmc_icache_miss_get ( NRF_NVMC_Type const * p_reg )

Function for getting the number of ICache misses.

Parameters

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

Return values

Number of the ICache misses.

__STATIC_INLINE bool nrf_nvmc_icache_profiling_enable_check ( NRF_NVMC_Type const * p_reg )

Function for checking if the ICache profiling option is enabled.

Parameters

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

Return values

true	ICache profiling enabled.
false	ICache profiling disabled.

__STATIC_INLINE void nrf_nvmc_mode_set	(	NRF_NVMC_Type *	p_reg,
		nrf_nvmc_mode_t	mode
	)

Function for setting the NVMC mode.

Only activate erase and write modes when they are actively used. If Instruction Cache (ICache) is present, enabling write or erase will invalidate the cache and keep it invalidated.

Parameters

[in]	p_reg	Pointer to the structure of registers of the peripheral.
[in]	mode	Desired operating mode for NVMC.

__STATIC_INLINE void nrf_nvmc_nonsecure_mode_set	(	NRF_NVMC_Type *	p_reg,

	)

Function for setting the NVMC mode for non-secure Flash page operations.

Parameters

[in]	p_reg	Pointer to the structure of registers of the peripheral.
[in]	mode	Desired operating mode for NVMC.

__STATIC_INLINE void nrf_nvmc_page_erase_start	(	NRF_NVMC_Type *	p_reg,
		uint32_t	page_addr
	)

Function for starting a single page erase in the Flash memory.

The NVMC mode must be correctly configured with nrf_nvmc_mode_set before starting the erase operation.

Parameters

[in]	p_reg	Pointer to the structure of registers of the peripheral.
[in]	page_addr	Address of the first word of the page to erase.

__STATIC_INLINE void nrf_nvmc_page_partial_erase_start	(	NRF_NVMC_Type *	p_reg,

Parameters

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

Function for configuring the page partial erase duration in milliseconds.

Parameters

[in]	p_reg	Pointer to the structure of registers of the peripheral.
[in]	duration_ms	Page partial erase duration in milliseconds.

__STATIC_INLINE bool nrf_nvmc_ready_check ( NRF_NVMC_Type const * p_reg )

Function for checking if NVMC is ready to perform write or erase operation.

Parameters

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

Return values

true	NVMC can perform write or erase.
false	NVMC is busy and cannot perform next operation yet.

Function for starting the user information configuration registers (UICR) erase.

Parameters

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

__STATIC_INLINE bool nrf_nvmc_write_ready_check ( NRF_NVMC_Type const * p_reg )

Function for checking if NVMC is ready to accept the next write operation.

NVM writing time can be reduced by using this function.

Parameters

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

Return values

true	NVMC can accept the next write. It will be buffered and will be taken into account as soon as the ongoing write operation is completed.
false	NVMC is busy and cannot accept the next write yet.
