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:
addressStart 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:
addressAddress to write to.
valueValue to write.
void nrf_nvmc_write_bytes ( uint32_t  address,
const uint8_t *  src,
uint32_t  num_bytes 
)

Write consecutive bytes to flash.

Parameters:
addressAddress to write to.
srcPointer to data to copy from.
num_bytesNumber 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:
addressAddress to write to.
valueValue to write.
void nrf_nvmc_write_words ( uint32_t  address,
const uint32_t *  src,
uint32_t  num_words 
)

@

Write consecutive words to flash.

Parameters:
addressAddress to write to.
srcPointer to data to copy from.
num_wordsNumber of bytes in src to write.
