TMS320F28335: 上电运行后，pwm有几次高低电平翻转，请问是哪里配置出了问题么。

请贴出完整PWM初始化代码来分析问题

您好，这是我的配置，请帮忙看一下是否配置正确，谢谢。

*在PCLKCR1寄存器中启用ePWM模块时钟。
•将TBCLKSYNC设置为0。
•配置预分频器值和ePWM模式。
•将TBCLKSYNC设置为1

DSP2833x_SysCtrl.c文件

SysCtrlRegs.PCLKCR0.bit.TBCLKSYNC = 0; // Disable TBCLK within the ePWM
SysCtrlRegs.PCLKCR1.bit.EPWM1ENCLK = 1; // ePWM1
SysCtrlRegs.PCLKCR1.bit.EPWM2ENCLK = 1; // ePWM2
SysCtrlRegs.PCLKCR1.bit.EPWM3ENCLK = 1; // ePWM3

SysCtrlRegs.PCLKCR1.bit.EPWM6ENCLK = 1; // ePWM6
SysCtrlRegs.PCLKCR0.bit.TBCLKSYNC = 1; // Enable TBCLK within the ePWM
