Function Documentation

void nvram_write	(	nvram_addr_t	addr,
		const void *	buf,
		uint16_t	size
	)

Name: nvram_write
Writes a buffer into NVRAM.

Parameters

addr	The address in NVRAM to which the buffer should be written.
buf	A pointer to the buffer from which data is to be read.
size	The number of bytes to write into NVRAM.

void nvram_read	(	nvram_addr_t	addr,
		void *	buf,
		uint16_t	size
	)

Name: nvram_write
Reads data from the NVRAM.

Parameters

addr	The address in NVRAM from which the data should be read.
buf	A pointer to the buffer to which the data should be stored.
size	The number of bytes to read.
