EPwm1Regs.AQCSFRC.all = 0xC;
EPwm1Regs.AQCSFRC.all = 0x0;怎么区别呢?我看了数据手册,AQCSFRC的CSFB CSFA各包括四种模式:
00:Forcing disabled, i.e., has no effect
01:Forces a continuous low on output B(强制B通道连续输出低)
10:Forces a continuous high on output B(强制B通道连续输出高)
11:Software forcing is disabled and has no effect
但是不能理解00和11有什么区别呢?请高手指点,谢谢 |
