说明：  飞思卡尔POWER PC系列芯片片上温度传感器驱动 直接返回温度值
(MPC5634M MCUs include an onboard temperature sensor that monitors device temperature and produces a voltage directly proportional to the internal junction temperature. Internal junction temperature must be calculated by software based on the sampled temperature sensor voltage, sampled bandgap voltage and calibration parameter values stored in internal flash memory.)
