eTMR输出PWM波形，配置完后，频率是正确的，但是占空比不正确

[wangzhen]

我使用eTMR2 ch3输出PWM波形，用逻辑分析仪抓取波形发现，频率是25K和设置的一样，但是占空比我设置的75%，但实测是95%，我确认了寄存器MOD=4799，VAL0=599,VAL1=4199,寄存器计算出来应该是75%，但是为什么波形抓出来是95%？

看下这个结构体的配置

etmr_pwm_sync_t ETMR_CM_Config2PwmSync={
.regSyncFreq=1,
.regSyncSel=REG_SYNC_WITH_MOD,
.cntInitSyncSel=CNT_SYNC_WITH_REG,
.maskOutputSyncSel=CHMASK_SYNC_WITH_REG,

.hwTrigFromTmuEnable=false,
.hwTrigFromCimEnable=false,
.hwTrigFromPadEnable=false,
};

问题已经确认是硬件的原因了，感谢！
