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
srcthe read source in the NVRAM address space
dstthe destination buffer in program data memory space
countthe 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
dstthe write destination in the NVRAM address space
srcthe source buffer in program data memory space
countthe 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
dstthe write destination in the NVRAM address space
srcthe source buffer in program data memory space
countthe number of Bytes to write
Returns
Nothing.
