注意七点：（1）sfrb：c430中新增的变量类型，占用一个字节，取值范围：0X00～0XFF，表示字节类型的特殊功能寄存器变量
（2）sfrw：c430中新增的变量类型，占用两个字节，取值范围：0X100～0X1FF，表示字（双字节）类型的特殊功能寄存器变量
（3）pointer：c430中新增的变量类型，占用两个字节，表示指针
特殊关键字说明：
（4）const：定义常量，这些量一旦定义就不能更改，可以定义任意类型
（5）static：定义静态变量，这种变量定义后，变量的地址是固定的，这些变量不会随着函数调用的结束而结束
（6）volatile：与static变量相反，这种变量明确告诉编译器，这类变量值随时会改变，不能对这种类型的变量优化删除任何操作过程
（7）no_init或_no_init:定义无需初始化的变量，c程序main（）函数开始运行前，会将所有RAM清零（初始化），对这种变量在此过程中不予清零处理。

在MSP430中，取消了位变量，通常采用由变量和掩膜位间的逻辑运算操作来实现位运算。
(1)例如：对p1.0口置位（置1）可以使用以下三种方法：
P1OUT |= 0X01;
P1OUT |= (1 << 0)
若已包含以上的头文件：
P1OUT |= BIT0;
(2)例如：对p1.0口复位（置0）可以使用以下三种方法：
P1OUT &= ～0X01;
P1OUT &= ～(1 << 0)
若已包含以上的头文件：
P1OUT &= ～BIT0;
(3)例如：对P1.0和P1.1口置位，对P1.2和P1.3口复位：
P1OUT |= 0X03; 或 P1OUT |= BIT0 + BIT1;
P1OUT &= ～0X06H；或 P1OUT &= ～（BIT2 + BIT3)；
