Enumeration Type Documentation

nrf_ramc_event_t

enum nrf_ramc_event_t

RAMC events.

Enumerator
NRF_RAMC_EVENT_ERROR_FIXABLE	ECC detected fixable (one bit) error in read data from RAM.
NRF_RAMC_EVENT_ERROR_NON_FIXABLE	ECC detected non-fixable (multiple bits) error in read data from RAM.

Function Documentation

nrf_ramc_event_address_get()

NRF_STATIC_INLINE uint32_t nrf_ramc_event_address_get	(	NRF_RAMC_Type const *	p_reg,
		nrf_ramc_event_t	event
	)

Function for returning the address of the specified RAMC event register.

Parameters

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

Returns

Address of specified event register.

nrf_ramc_event_check()

NRF_STATIC_INLINE bool nrf_ramc_event_check	(	NRF_RAMC_Type const *	p_reg,
		nrf_ramc_event_t	event
	)

Function for retrieving the state of the RAMC event.

Parameters

[in]	p_reg	Pointer to the structure of registers of the peripheral.
[in]	event	Event to be checked.

Return values

true	The event has been generated.
false	The event has not been generated.

nrf_ramc_event_clear()

NRF_STATIC_INLINE void nrf_ramc_event_clear	(	NRF_RAMC_Type *	p_reg,
		nrf_ramc_event_t	event
	)

Function for clearing the specified RAMC event.

Parameters

[in]	p_reg	Pointer to the structure of registers of the peripheral.
[in]	event	Event to be cleared.

nrf_ramc_secbase_get()

NRF_STATIC_INLINE uint32_t nrf_ramc_secbase_get

(

NRF_RAMC_Type const *

p_reg

)

Function for getting base address for secure access area.

Parameters

[in]

p_reg

Pointer to the structure of registers of the peripheral.

Returns

Base address.

nrf_ramc_secbase_set()

NRF_STATIC_INLINE void nrf_ramc_secbase_set	(	NRF_RAMC_Type *	p_reg,
		uint32_t	addr
	)

Function for setting base address for secure access area.

Note

When the SECENABLE is enabled, any non-secure accesses to the address within the RAM which are above or equal to the base address generates an error.

Parameters

[in]	p_reg	Pointer to the structure of registers of the peripheral.
[in]	addr	Base address. Writes to the bits [11:0] are ignored and are read as zero. Similarly, the MSB size depends on the size of the RAM, writes to those MSB above the size are ignored and are read as zero.

nrf_ramc_secenable_check()

NRF_STATIC_INLINE bool nrf_ramc_secenable_check

(

NRF_RAMC_Type const *

p_reg

)

Function for checking secure access restrictions.

Parameters

[in]

p_reg

Pointer to the structure of registers of the peripheral.

Return values

true	Secure access restrictions are enabled.
false	Secure access restrictions are disabled.

nrf_ramc_secenable_set()

NRF_STATIC_INLINE void nrf_ramc_secenable_set	(	NRF_RAMC_Type *	p_reg,
		bool	enable
	)

Function for setting secure access restrictions.

Parameters

[in]	p_reg	Pointer to the structure of registers of the peripheral.
[in]	enable	True if secure access restrictions are to be enabled, false otherwise

nrf_ramc_waitstates_get()

NRF_STATIC_INLINE uint8_t nrf_ramc_waitstates_get

(

NRF_RAMC_Type const *

p_reg

)

Function for getting number of waitstates for a read from the RAM.

Parameters

[in]

p_reg

Pointer to the structure of registers of the peripheral.

Returns

Number of waitstates.

nrf_ramc_waitstates_set()

NRF_STATIC_INLINE void nrf_ramc_waitstates_set	(	NRF_RAMC_Type *	p_reg,
		uint8_t	waitstates
	)

Function for setting number of waitstates for a read from the RAM.

Parameters

[in]	p_reg	Pointer to the structure of registers of the peripheral.
[in]	waitstates	Number of waitstates [0...1].
