尊敬的团队：
有关 CBC 函数、我有两个问题：
1、我们已经编辑 了一个 CBC 程序参考 F28035的示例程序、它在 LAUNCHXL-F280049C 上运行良好。 但它无法在 自己设计的电路板上工作。
如果我们禁用 CBC 功能、它可以在我自己的板上正常工作。 可能的原因是什么？
2、当我使用 LAUNCHXL-F280049C 运行程序时、为什么 即使 EPwm1Regs.TZCBCFLG.DCAEVT2 =1且 DCBEVT2=1、它也能有 PWM 输出？
但是、我自己设计的电路板仍然没有输出。
此外、您是否有 任何有关 F280049的 cmpss、X-bar、TZDC、CBC 的示例程序？
以下是我的计划：
