Can we obtain the number of pulses that have already been emitted when using the RMT transmission pulse sequence of EPS3

I hope to use the RMT module of ESP32-S2 to send a fixed number of PWM waves, and use the cyclic transmission mode of the RMT module. When the cyclic transmission mode is enabled and transmission begins, can the number of cycles that have been sent be obtained in real-time in the program?

Hello,I have reviewed these documents and there are no related functions or registers for reading the number of loops

No.
no, this option is not available
esp32s2 allows you to set the number of repetition cycles
What is the maximum number of PWM waves?

I want to use ESP32s2 to control the servo motor for positioning control, with a maximum pulse count of around 200k
