这是个宏定义，从代码字面的意思是把 GPF0_in 代换成 ~(3<<(0*2))之所以这样代换，是有其原因的：ARM GPIO引脚里面有好几组，这里把GPF组的0号引脚配置成输入（in）模式，而~(3<<(0*2))的意思是除了最低两位〔1，0〕是00外，其他位都是设置成1。（如果不能明白这些操作的话，认真看看...

This combination may seem counterintuitive at first, but it's key to the fundamental promise of ARM64EC being interoperable with x64 code even within the same binary. Windows 11 takes care of seamlessly transitioning between code running natively in the CPU and under emulation. To do so, i...
