Oscar has covered Oneshot 125 and Multishot, but there doesn't seem to be much info around Oneshot 42 so I will try to fill the gap here with my limited experience.
Some background before we move on:
OneShot125 is basically an alternative PWM signal from the ESC to the motors. Its 8 times faster than the standard PWM signal. Available on most SimonK, BLHeli and old KISS ESCs.
Multishot is 10 times faster than Oneshot125, and 80 times faster than standard PWM.
There is nothing secret on oneshot42, it's similar to Oneshot125, but the speed is somewhere in the middle of the other 2 protocols, being just 3 times faster than the OneShot125. It's developed by Flyduino for the KISS ESC and FC.
Its the same as oneshot 125 just another 3 times faster.
Oneshot 42 still has fully 1000 steps of resolution as it uses a 24mhz timer on the ESC side and uses 42us as the base. Assuming it follows standard Oneshot timing that means 42-84us pulses. With it, those who want can have 12khz looptimes
