F28377D 的 hrpwm问题

你好，HRPWM口可以参考芯片手册33页和34页表格的标注。
例程代码第31行：updates HRMSTEP register (exists only in EPwm1Regs register space)

您的理解是正确的。

The HRMSTEP is only on EPWM1 and is shared for all PWMs with HR capability. Everything related to all HRPWMs calibration is shared and only accessed by ePWM1 register space.

These registers only exist in the ePWM1 register space. They cannot be accessed from any other ePWM module’s register space.
