Changing pin state: ISA Question
Hello, I'm new to uCs. I intend to buy some. I'm just not sure which type.
I've read that with AVR, you have to read-modify-write a register in order to change a single pins value, whereas with ARM, you just change a whole byte and the pin is set to high or low.
How does the ESP32s work?
Thanks

Re: Documentation Requests/Feedback
Chalk another request for the ISA docs. I can get the ISA docs without an NDA for x86, amd64, ARM, and AVR. What's the hold up?

Re: ESP32 ISA reference manual
This is so strange. I can get ISA docs on x86, amd64, ARM, and AVR, but not Xtensa. Maybe a direct request to Cadence would help. Also interesting is that you could, in theory, reverse engineer the docs from the gcc code to translate programs to LX6 assembly, but nobody appears to have done that yet...

ESP32 ISA reference manual
Hi, I'm considering the purchase of some ESP32 based boards and I was searching for the ISA reference manual for the core. I've searched https://www.espressif.com/en/support/download/documents , https://docs.espressif.com/projects/esp-idf/en/latest/ , https://en.wikipedia.org/wiki/ESP32 , and I've d...
