ESP32-C3 RISC-V Assembly GPIO control

I have a few different kinds of ESP32-C3s that I am playing around with and I want to use small amounts of assembly code to send pulses to a GPIO pin. I found the GPIO memory address in a technical manual Table 3­4. Module/Peripheral Address Mapping here. What I am completely lost on is, how do I access a pin, and how do I set the pin high, and after that, how can I time those instructions? I'm a little lost on where to start for all of this. How would I go about finding the information I need for the pins and instructions?
