FIQ有FIQ_PWM、FIQ_TMA和FIQ_TMB三个中断源,当定时器A或B计满溢出时产生中断请求信号TA_TIMEOUT_INT或TA_TIMEOUT_INT,CPU响应后进入中断执行相应的子程序控制二极管发光。A口的低四位接LED灯，B口的低四位接LED灯.-FIQ has FIQ_PWM, FIQ_TMA and FIQ_TMB three interrupt sources, when the timer A or B when the expiration overflow interrupt request signal TA_TIMEOUT_INT or TA_TIMEOUT_INT, CPU response after interruption of the implementation of the corresponding subprogram control light-emitting diodes. A low population of four LED lights then, B I take the low four LED lights.
