BPROT HAL
- group nrf_bprot_hal
Hardware access layer for managing the Block Protection (BPROT) mechanism.
Functions
-
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
p_reg – [in] Pointer to the structure of registers of the peripheral.
group_idx – [in] Non-volatile memory group containing memory blocks to protect.
block_mask – [in] Non-volatile memory blocks to protect. Each bit in bitmask represents one memory block in the specified group.
-
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
p_reg – [in] Pointer to the structure of registers of the peripheral.
enable – [in] True if NVM protection during debug is to be enabled, false otherwise.
