TMS320F280049C: 是否可以配置EPWMxA占空比波形，xB配置带死区的高低电平

（1）目前我们的方案是有感BLDC电动工具，但是没有找到类似280049的有感BLDC电机驱动的工程。如果采用无感BLDC的280049工程再从2803x的有感BLDC移植过来这样可行？

（2）我已从《HVBLDC_Sensored》的2803x的设计文件<f2803xbldcpwm.h>看到类似这样的配置，移植过来用示波器测试还没有发出波形。只有A是高电平，B是低电平，不配成互补波形的话，需要配哪些寄存器？这个地方对我来说还是比较难，能否有280049有感bldc六步换相跑得起来的寄存器配置？

（3）我要做BLDC有感电动工具，建立比较好的工程，您有什么建议的？

（4）以下是移植过来的配置寄存器代码
