Right, I know about the WP/HD lines in quad mode. I was hoping to abuse at least one line for the #C/D line of an OLED SPI display to automate setting the row address without two separate SPI transactions, but I guess I'll just bite the bullet and live with toggling a GPIO and waiting for the comman...

Can I get a little clarity on how the #WP pin is used on the SPI master drivers? The only thing the documentation mentions is the WP idle level, but it doesn't have any description of how the pin toggles when in use (esp. with regards to the command/address/data phases). Some of that can be inferred...

I'm actually also very interested in the motor control PWM for determining suitability of the ESP32 for a task or two (unsurprisingly, related to motor controls). Is there any way I could get a peek at info about it, or is it similar to other modules (say, on the ESP8266)? I could possibly use the L...
