typedef uint16_t nvram_addr_t

Data type for NVRAM memory addresses.

void nvram_read	(	nvram_addr_t	src,
		void *	dst,
		size_t	count
	)

Read a buffer from non-volatile RAM.

This routine reads count Bytes from the NVRAM source pointed to by src to the destination buffer pointed to by dst.

Parameters

src	the read source in the NVRAM address space
dst	the destination buffer in program data memory space
count	the number of Bytes to read

Returns

Nothing.

void nvram_write	(	nvram_addr_t	dst,
		const void *	src,
		size_t	count
	)

Atmel platform non-volatile memory spaces.

Write a buffer to non-volatile RAM

This routine writes count Bytes to the NVRAM destination pointed to by dst from the source buffer pointed to by src.

Parameters

dst	the write destination in the NVRAM address space
src	the source buffer in program data memory space
count	the number of Bytes to write

Returns

Nothing.

Atmel platform non-volatile memory spaces.

This routine writes count Bytes to the NVRAM destination pointed to by dst from the source buffer pointed to by src.

Parameters

dst	the write destination in the NVRAM address space
src	the source buffer in program data memory space
count	the number of Bytes to write

Returns

Nothing.
