Other Parts Discussed in Thread: CONTROLSUITE
Dear TI support：
根据应用场景，280049的三路EPWM需要配置如下图所示的波形，官方并无此配置。
但是从C:\ti\controlSUITE\development_kits\HVMotorCtrl+PfcKit_v2.0\HVBLDC_Sensored可以看到这种配置，但是移植过来并无作用，似乎配置得并不完整。
如EPwm3Regs.AQCTLA.all = BLDCPWM_AQCTLA_INIT_STATE;
#define BLDCPWM_AQCTLA_INIT_STATE CAU_SET
这是显然不对的。
所以我自己配置了一段240049的EPWM寄存器，但是PWM波形换相有比较大的延时。请问官方是否有这样的准确标准的配置波形？
以下是我的配置寄存器，麻烦你帮我看看有什么地方不对的。

我查看了霍尔波形和pwm波形，换相时，H_PWM和L_ON没有立即生效。这个在哪里改呢
