Design first, code later. Plan everything out using logic, flow diagrams, state diagrams, etc. Your problems are with the logic, not the coding. Jonk has done 8051, I have not. I have done 6502 and 6800 assembly, these are similar.
At first you might be tempted to have states based on physical position.
But, an elevator really only has 3 states, going up, ...

Using the following code we can obtain the path the poles go as you change k.
G = poly([-1],'z')/poly([0.3 1],'z');
figure;
evans(G,10)
zgrid;
y = [];
for k = logspace(-2,1,1000)
y = [y abs(roots((k*G/(1+k*G)).den))];
end
figure;
plot2d("ll",logspace(-2,1,1000),y')
legend('a1','a2')
//pick here your optimal gain
L = 0.5*G;
L = L/(1+L);
t = 0:21;

As @Elliot Alderson pointed out the comment below maybe i need to investigate IBIS models and try to implement that as proper way to acheive the mapping between the two different formulations.

$$\ddot{\Theta}=\dfrac{1-K_d\cdot\dot{\Theta}}{J} $$
$$J\ddot{\Theta}+K_d\cdot\dot{\Theta}-1=0 $$
$$\ddot{\Theta}+\dfrac{K_d}{J}\cdot\dot{\Theta}-\dfrac{1}{J}=0 $$
Discriminant : \$ \dfrac{K_d^2}{J^2} -\dfrac{4}{J}\$ is it positive?
$$\dot{i} = \dfrac{1}{L}(V-K_g k_f \dot{\Theta}-R i)$$
$$i = \dfrac{1}{L}\int(V-K_g k_f \dot{\Theta}-R i)dt$$
You solve the ...

I had the same issue. As you can see when you used the verbose mode it listed all the fuses you have : fuse0, fuse1, fuse2 ...
If you type avrdude.exe -c jtag2_updi -p attiny1616 -U fuse0:r:-:i -v it will show you the value written in fuse 0 which is the WDTCFG fuse.
So fuse0 to fuse9 correspond respectively to fuses with offset 0x00 to 0x09 (page 33 in ...
