位屏蔽的含义是从包含多个位集的一个或一组字节中选出指定的一(些)位。为了检查一个字节中的某些位，可以让这个字节和屏蔽字(bit mask)进行按位与操作(C的按位与运算符为＆)——屏蔽字中与要检查的位对应的位全部为1，而其余的位(被屏蔽的位)全部为0。例如，为了检查变量flags的最低位，你可...

CPU firmware may initialize GPIO pins to have alternate input or output functions as listed in Table 8. At any time, the logic state of any GPIO pin may be read by firmware as a GPIO input, regardless of its reassigned input or output function. Bit masking is available on each port, ...

Then when you paint, the masking tape blocks the paint from reaching anything you don’t want painted. In the end, only the non-masked parts (the parts you want painted) get painted.A bit mask essentially performs the same function for bits -- the bit mask blocks the bitwise operators ...
