From the datasheet, I see that there is a Bitscrambler peripheral that seems to be very similar in flexibility to the Raspberry Pi Pico's PIO:

> Since bitwise operations can be relatively CPU-intensive and DMA is designed specifically to offload such work from the CPU, ESP32-S31 integrates two dedicated peripherals called BitScramblers. These modules are designed to transform data formats during transfers between memory and peripherals. One BitScrambler handles memory-to-peripheral (or memory-to-memory) transfers, while the other is dedicated to peripheral-to-memory transfers. While BitScramblers can handle the bitwise operations mentioned earlier, they are in fact flexible, programmable state machines capable of performing more advanced transformations as well.

Here's hoping that it's as useful as the Pi Pico's PIO

neat!
