NVM是非易失性存贮器的意思，包括EEPROM和FLASH，我以前总以为是中断控制的东东。
首先建立ASF工程，
然后加入NVM模块。
打开ASF EXPLORER中的快速指导。
最后打断点调试，看看程序执行没有。
以下是程序执行结果截图。
程序清单如下：
/**
* \file
*
* \brief Empty user application template
*
*/
/**
* \mainpage User Application template doxygen documentation
*
* \par Empty user application template
*
* This is a bare minimum user application template.
*
* For documentation of the board, go \ref group_common_boards "here" for a link
* to the board-specific documentation.
*
* \par Content
*
* -# Include the ASF header files (through asf.h)
* -# Minimal main function that starts with a call to system_init()
* -# Basic usage of on-board LED and button
* -# "Insert application code here" comment
*
*/
/*
* Include header files for all drivers that have been imported from
* Atmel Software Framework (ASF).
*/
void configure_nvm(void);
#include <asf.h>
void configure_nvm(void)
{
struct nvm_config config_nvm;
nvm_get_config_defaults(&config_nvm);
nvm_set_config(&config_nvm);
}
int main (void)
{
system_init();
configure_nvm();
uint8_t page_buffer[NVMCTRL_PAGE_SIZE];
for (uint32_t i = 0; i < NVMCTRL_PAGE_SIZE; i++) {
page_buffer[i] = i;
}
enum status_code error_code;
do
{
error_code = nvm_erase_row(
100 * NVMCTRL_ROW_PAGES * NVMCTRL_PAGE_SIZE);
} while (error_code == STATUS_BUSY);
do
{
error_code = nvm_write_buffer(
100 * NVMCTRL_ROW_PAGES * NVMCTRL_PAGE_SIZE,
page_buffer, NVMCTRL_PAGE_SIZE);
} while (error_code == STATUS_BUSY);
do
{
error_code = nvm_read_buffer(

page_buffer, NVMCTRL_PAGE_SIZE);
} while (error_code == STATUS_BUSY);
while(1);
}
