As long as you trust the generated signal is within the published timings, and not just what the logic analyzer accepts.

If you mix the tuna (packed in water, not oil) with Miracle Whip and add just a tiny bit of pickle relish -- served on multi grain bread.... with Vinegar & Sea Salt potato chips (crisps to some?) on the side. Mmmm

And where are you if given the choice between an IPA or a Guinness Draught to enjoy with your Tuna Sandwich and chips? (I'm firmly in the Guinness camp.)

More years ago than I like to remember, I was working on the programming for an industrial laser (1KW CO2). This was supposed to run the laser at the command of a CNC, but the documentation was not all that could have been desired.
We were reduced to similar expedients to ensure that we got good communication between the CNC and out hardware. Having an out-of-control 1KW laser running loose is no joke!

Did that one myself. I wrote the control software for a machine with three visible light red, green, and blue lasers, along with an IR laser. The red, green, and blue lasers were pretty safe, but the IR was not. There were interlocks on all of the doors that cut laser power if the doors were opened.
Also, as protection against the soft schmuck making a mistake, the s/w had to toggle a bit on a port once a second to maintain power to the entire machine.

Waaayyyy back in the time, I had to bit bang a 1200 baud serial port while driving the pins and motors on a slip printer.
Managed this on a 6801/3/5 by using state machines stepped by a timer, or timers, interrupt(s).
Very accurate and easy to tweak.
Good luck.

I wish i could use a timer like that, but the timing is too tight for this. It's gotta be clock cycle accurate.
You run into a similar problem on the old Nintendo since it didn't have a frame buffer and the CPU, while faster than the scan gun, still wasn't that fast.
So you had to cycle count to plot, following the scan gun top to bottom, left to right until you reached the end.
On a faster system you could use a timer for that.

I did that on a PIC microcontroller once. We needed a one-second signal and a 15-minute signal, and the only timing reference was the CPU clock. Lots of pre-calculated values, NOP's and such, all in a single page of code. Lots of fun  .

This is kind of like that except I have to dynamically generate the code. It's because the line changes on a USB interface are so tightly timed, and just ... i don't know if there's another way to do it.

My approach worked only because I knew the CPU clock frequency accurately and the project was a one-off.

I predict you will enjoy creating it and getting it to work.
I also predict you will loathe it the first time it goes sproing.

We have a member who has reached an amazing 385 questions: a Help Vampire par excellence!
I can only assume that we are supporting his entire employment as he doesn't seem to have learned much (if anything) over the years.
Can we split his salary between us, or would that be unfair?

Even more impressive, his first QA question was in December 2016. That's an average of 70 "do my work for me" questions per year, not counting any which have been closed.
I'm surprised he didn't take a day off yesterday to travel to Whitby[^].

I'd like to draw your attention to the post below about making friends, and the reaction I assigned to the post.
It counted my reaction twice and I think I'm the only member who has had his reaction recorded twice for one post.
