void wait( unsigned short int loop); Global variables and functionsの中にwait関数プロトタイプを記入します。

void main(void)何も記述しません。自動で出来上がった無限ループだけです。

static void R_MAIN_UserInit(void) 自動生成で出来た R_TAU0_Channel0_Start();と R_ADC_Set_OperationOn(); を呼び出してタイマーとA/Dコンバータを起動させます。

void wait( unsigned short int loop)タイミングループです。
