Each PWMSSn ePWM/eHRPWM module has an EPWMTBCLKEN module input used to individually enable/disable its ePWM time-base clock. For each PWMSSn (where n=1 to 3), the ePWM/eHRPWM time-base clock enable input comes from the device core control module register - CTRL_CORE_CONTROL_IO_2, as follows:
This individual TBCLKEN control can be used to align the ePWM time base clock between the three device PWMSS subsystems. PWMSSn_TBCLKEN bit set to 0b0, holds the TBCLK generation counter in its reset state. When PWMSSn_TBCLKEN is set to 0b1, then the TBCLK generation counter is allowed to count.
For more details on the CTRL_CORE_CONTROL_IO_2, refer to the Control Module Register Manual, in the chapter Control Module.
