ADC/RTC/TWI/USARTライブラリ内から処理待ちのときに呼び出される関数。

main.cppなどにavr8_yield()を定義したときだけ呼び出される。

【サンプルコード (Microchip Studio)】

#include "avr8_xxx.h"

void avr8_yield(void)
{
  /* 処理待ちのときライブラリ内から呼び出される */
}

int main(void)
{
  ...
}

#include "avr8_xxx.h"

void avr8_yield(void)

{

/* 処理待ちのときライブラリ内から呼び出される */

}

int main(void)

{

...

}
