Detailed Description

Hardware access layer for managing the Block Protection (BPROT) mechanism.

Function Documentation

nrf_bprot_nvm_blocks_protection_enable()

NRF_STATIC_INLINE void nrf_bprot_nvm_blocks_protection_enable	(	NRF_BPROT_Type *	p_reg,
		uint8_t	group_idx,
		uint32_t	block_mask )

Function for enabling protection for specified non-volatile memory blocks.

Blocks are arranged into groups of 32 blocks each. Each block size is 4 kB. Any attempt to write or erase a protected block will result in hard fault. The memory block protection can be disabled only by resetting the device.

Parameters

[in]	p_reg	Pointer to the structure of registers of the peripheral.
[in]	group_idx	Non-volatile memory group containing memory blocks to protect.
[in]	block_mask	Non-volatile memory blocks to protect. Each bit in bitmask represents one memory block in the specified group.

nrf_bprot_nvm_protection_in_debug_set()

NRF_STATIC_INLINE void nrf_bprot_nvm_protection_in_debug_set	(	NRF_BPROT_Type *	p_reg,
		bool	enable )

Function for setting the non-volatile memory (NVM) protection during debug.

NVM protection is disabled by default while debugging.

Parameters

[in]	p_reg	Pointer to the structure of registers of the peripheral.
[in]	enable	True if NVM protection during debug is to be enabled, false otherwise.
