HRPWM模块的MEP的边沿控制有上升沿、下降沿、上升沿与下降沿，手册描述入戏：
The MEP can be programmed to provide precise position control on the dead band rising
edge (RED), dead band falling edge (FED) or both edges (rising edge of DBRED signal and falling
edge of DBFED signal ) at the same time
请问这里的上升沿是指PWM在AQ和DB寄存器动作之后输出脉冲的上升沿中在寄存器中加入CMPHR的微调值吗？
