FAULTMASK位:只允许NMI,其他所有中断/异常都被屏蔽(当前CPU优先级=-1)。 在STM32固件库中(stm32f10x_nvic.c和stm32f10x_nvic.h) 定义了四个函数操作PRIMASK位和FAULTMASK位,改变CPU的当前优先级,从而达到控制所有中断的目的。 下面两个函数等效于关闭总中断: voidNVIC_SETPRIMASK(void);voidNVIC_SETFAULTMASK(v...

PRIMASK和FAULTMASK寄存器在很多应用中需要暂时屏蔽所有的中断进行一些对时序要求较高的任务,不然容易发生bug,例如I2C通讯。此时可以使用PRIMASK寄存器。PRIMASK可以屏蔽 60user1572021-08-13 07:20:53 STM32开关总中断方法盘点 ();//开放总中断 补充可以用 #define CLI() __set_PRIMASK(1) #define SEI() __set_...
