attachInterrupt( ) - modes ONLOW_WE & ONHIGH_WE, how do they work?

[Algonsi]

Hello, I have searched everywhere to know how interrupts work with ONLOW_WE and ONHIGH_WE modes, but I have not been able to find anything about it.
Please does anyone know what those two interrupt modes are for?

Do these modes exist?
I found nothing ...

I guess so, since you can find them in Arduino.h, line 56:

//Interrupt Modes
#define RISING    0x01
#define FALLING   0x02
#define CHANGE    0x03
#define ONLOW     0x04
#define ONHIGH    0x05
#define ONLOW_WE  0x0C
#define ONHIGH_WE 0x0D

So, in simple words, ONLOW_WE will trigger an interrupt if the input signal level is low (not a falling edge) and wake up the ESP32 from light sleep, if it is currently in light sleep.
