void main(void){
}
After the PPG pulse output is started by the program and the buzzer starts sounding, the
buzzer sound cannot be stopped even when the stop button on the ACCEMIC screen is
clicked. This is because the PPG timer continues operation and pulse output is not
stopped even when the CPU stops. To stop the buzzer, press the stop button and then
reset the microcomputer.
Descriptions ”IO_XXX.byte” and ”IO_YYY.bit” included in the above program code are
the convenient formats of description defined in the I-O header file.
