手册中我看到timer 有break的功能, 内部还有 内部比较器的.
我的应用情况是如下 内部比较器的输出COMP1_OUT 和 TIM1_BKIN 内部相连
对于TIM1_BK 我阅读到以下内容:
When one of the breaks occurs (selected level on one of the break inputs):
• The MOE bit is cleared asynchronously, putting the outputs in inactive state, idle state
or even releasing the control to the GPIO controller (selected by the OSSI bit). This
feature is enabled even if the MCU oscillator is off.
关闭PWM输出的过程 不是由软件实现的, 是靠mcu内部硬件实现的, 这个过程的延时时间是多少 ?
