TMS320F280049C: about CLA

C YG

Part Number: TMS320F280049C

在配置好CLA后发现调用EPWM4时会报错，因此更改了CMD文件中地址的大小，发现将CLA所用的地址范围加大后调用EPWM4不再报错，但是这个时候通过在线仿真可以看到duty值不再变化。在没修改CMD文件之前duty值是在变化的，修改之后虽然duty值没有变一直为0，但是我在CLA里将GPIO12拉高，通过示波器观察GPIO12确实为高电平，因此可以认为此时CLA在运行，只不过CLA中的变量duty值不变。

应该是我修改CMD文件的地址范围导致的，这个怎么解决？duty值不变是为什么？
