BOD33是用来监视，3.3伏电压，若低于电压就重新启动。
首选建立ASF工程，添加BOD33模块，
然后打开，ASF EXPLORER点开快速指导。然后根据提示形成程序
以下是程序编译通过的截图：
由于开发板供电充足所以没有办法实测，只是等着以后开发时看看通否用到该功能吧。
程序清单：
/**
* \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_bod33(void);
#include <asf.h>
void configure_bod33(void)
{
struct bod_config config_bod33;
bod_get_config_defaults(&config_bod33);
bod_set_config(BOD_BOD33, &config_bod33);
bod_enable(BOD_BOD33);
}
int main (void)
{
system_init();
configure_bod33();
// Insert application code here, after the board has been initialized.
// This skeleton code simply sets the LED to the state of the button.
while (1) {
}
}
