28335的epwm的时基模块TBCTR用的是哪个定时器啊?能人为关闭和使能吗?换句话说，能在程序里任意时刻人为关闭或者使能pwm的载波呢?
或者说某一时刻我在开启使能TBCLKSYNC，开启载波三角波的时候，SysCtrlRegs.PCLKCR0.bit.TBCLKSYNC = 1，有什么办法能让TBCTR重新从0开始计数？我试了装初值如下：
EALLOW; SysCtrlRegs.PCLKCR0.bit.TBCLKSYNC = 0;// Enable TBCLK within the ePWM EDIS; EPwm1Regs.TBCTR = 0x0000; EALLOW; SysCtrlRegs.PCLKCR0.bit.TBCLKSYNC = 1;// Enable TBCLK within the ePWM EDIS;
但是好像不行
SysCtrlRegs.PCLKCR0.bit.TBCLKSYNC = 0;// Enable TBCLK within the ePWM
这个就是用来关时钟的，但是会关掉所有PWM的时钟。使能前如果要计数器清零，则直接写0即可。
