SFR_8BIT(CALDCO_16MHZ);对使用宏定义的地方进行字符展开就是：extern volatile unsigned char CALDCO_16MHZ；
CALBC1_1MHZ and CALDCO_1MHZ are two bytes programmed in the flash at the factory which are a calibrated value as to the VCO (voltage controlled oscillator)
of the chip. This means that when you load those two values into the respective registers, you are using a precalibrated setting to get appoximately 1MHz.
CALBC1_1MHZ and CALDCO_1MHZ是用来设置校准值的。TI已经把他放进flash中了。
头文件中有一行字：
/************************************************************

他的意思就是：存储在flash中的校准数据，0x10FFu 这些都是他们的地址
