Hacking Just a fun idea \ theoretical hardware question

[ClickCLK]

Just to get it out there: I'm sure that no one will try to develop this, so my question is mostly theoretical.

When programming a microcontroller, you can assign some function to one of the available pins to make a hardware button that will do something. For example, when building a homemade music player based on microcontroller you will need play\pause button, fast forward and rewind buttons, etc, so you program this functions in such a way that you can add hardware buttons and solder them to assigned pins, which will control this functions. I hope you get the idea.
So is it possible, with some clever coding, to assign software "forced boost mode" option switch of PS4 Pro to some unused register on any IC \ tespoint inside it, so you can add hardware button to switch this option on and off?

It will be extremely fun to have a modded ps4 pro with turbo button and "Lo\Hi" indicator, like on oldschool PCs of 1990's (seed spoiler below).

Hi/Lo lol.

Don't know that I ever had any saying high/low. Just 33 and 66, and 100 on one of the ones in school.

What you describe would want a fully hacked PS4. You might be able to do it without it though.

Is the clock generated internally? If there is some clock line and it is not just a multiplier you could sense it somehow. Might be an extra part rather than just a pin pulled one way or the other but as long as you just need sensing and not accurate reading then yeah, there might also be a way with power draw if you want to sense something in the power path.

Enabling it on the device would be slightly tricky. Seems you have to go into the settings to do it. It is predictable enough so you could probably write a macro into a controller, maybe even one that force closes the game first..

Just for t3h lulz.

I guess it's true that you can sense clock frequency, but it will be different in menu and inside a game, so I think this won't do as it will change the state of indicator by itself. Also, separate button that will change only "boost mode enabled" option is necessary, because even if one of this requisites will work different the whole point of fun in this mod will be lost.
