Likewise, whenever the driver creates an MCPWM capture timer instance, the driver guarantees that the power management lock is acquired when enabling the timer by :cpp:func:`mcpwm_capture_timer_enable`. And releases the lock in :cpp:func:`mcpwm_capture_timer_disable`.

{IDF_TARGET_NAME} supports to retain the MCPWM register context before entering **Light-sleep** and restore them after woke up. Which means you don't have to re-init the MCPWM driver after the **Light-sleep**.
This feature can be enabled by setting the flag :cpp:member:`mcpwm_timer_config_t::allow_pd` or :cpp:member:`mcpwm_capture_timer_config_t::allow_pd`. It will allow the system to power down the MCPWM in Light-sleep, meanwhile save the MCPWM register context. It can help to save more power consumption with some extra cost of the memory.
