i realized i messed up the oe mux and i havent drawn the fb mux
<astrobunny>
i noticed in the datasheet theres an inverter on the logic foldback
<astrobunny>
i guess it nots the logic feedback
<astrobunny>
i noticed also that in one of the files produced in the fitter it seems to have sent the dff output to the mc's flb
<astrobunny>
i wonder if theres another mux that selects if the y1 or output gets placed on the flb
<astrobunny>
because they seem to share that line
<astrobunny>
inb4 they are just a dangerous short and its up to the fitter to avoid a situation where they both drive it
<astrobunny>
strange thing is the output flb seems to go to the mc flb but the diagram in the datasheet shows it goes to the uim so i am a bit confused there
<astrobunny>
tried to poke the fitter to force it to use a logic foldback but it has so far refused my advances
<whitequark>
<astrobunny> "strange thing is the output..." <- the diagram in the datasheet is often wrong
<whitequark>
<astrobunny> "tried to poke the fitter to..." <- yeah this is really hard
<whitequark>
look at the fuzzing scripts for foldback
<whitequark>
astrobunny: so, i won't have time in the following days, but i propose we collaborate on this the next Sunday after tomorrow
<astrobunny>
no problem next sunday sounds good
<astrobunny>
also after spending some time on reading on the train, i realized i was conflating the logic *foldback* and output _feedback_
<astrobunny>
turns out Mx_FLB comes from logic and Mx_FB is something the uim can connect to, so the datasheet is okay
<astrobunny>
but my diagram isn't
<whitequark>
yes
<astrobunny>
ill try and make my rats nest more accurate first so i can assure myself i know what is going on. i think i more or less have the pieces i need to write a bit of verilog now
<astrobunny>
also it seems the older datasheets have much more info than the new ones
