Detailed Description

Driver for the nRF51 NVMC peripheral.

This driver allows writing to the non-volatile memory (NVM) regions of the nRF51. In order to write to NVM the controller must be powered on and the relevant page must be erased.

Function Documentation

void nrf_nvmc_page_erase

(

uint32_t

address

)

Erase a page in flash. This is required before writing to any address in the page.

Parameters

address

Start address of the page.

void nrf_nvmc_write_byte	(	uint32_t	address,
		uint8_t	value
	)

Write a single byte to flash.

The function reads the word containing the byte, and then rewrites the entire word.

Parameters

address	Address to write to.
value	Value to write.

void nrf_nvmc_write_bytes	(	uint32_t	address,
		const uint8_t *	src,
		uint32_t	num_bytes
	)

Write consecutive bytes to flash.

Parameters

address	Address to write to.
src	Pointer to data to copy from.
num_bytes	Number of bytes in src to write.

void nrf_nvmc_write_word	(	uint32_t	address,
		uint32_t	value
	)

Write a 32-bit word to flash.

Parameters

address	Address to write to.
value	Value to write.

void nrf_nvmc_write_words	(	uint32_t	address,
		const uint32_t *	src,
		uint32_t	num_words
	)

Write consecutive words to flash.

Parameters

address	Address to write to.
src	Pointer to data to copy from.
num_words	Number of bytes in src to write.
