22:28 2 different kinds I like to put on. 1 is on power amps.
10:01 So, yeah, that way you can disconnect different power rails. I like using it a lot for power rails because, let's say, you're designing a new switcher on your your prototype, new switch mode power supply, and you mess it up because you won't you will mess it up. Yeah. And but now it's like, well, in the past, you would have to go and, like, do surgery to, like, disconnect it from your rest of your circuit. And so you can bring it up, make sure it's outputting the 3.3 volts that you want to output or whatever the voltage it needs to be, and then you can connect it back up.
32:14 And the last thing I have is, I call it like utilizing all possibilities is every signal that you don't have hooked up. So, like, it let's say you even have a component that's got those indicators, like, power good and stuff, break them out to a test point anyways. Break everything out. Break anything that's not unused. You might be like, oh, it would be nice if this power subsystem if the microcontroller knew it was powered up fully.
