#PDP11 -40, a return from interrupt instruction. This is the way it should be: restore the PC and restore the flags.
Unfortunately, I caught glitches with my timer program for quite a long time due to the fact that the #avr does not restore the flags.
I do not know, guys, I have a feeling that the PDP11 had a smart and thoughtful system of commands, whereas the guys from Atmel...😉
I must admit that Qwant is searching good enough for me. Of course, not functioning in lynx and the absence of a dark theme in the light version spoils the whole impression.
My favorite unit in #Dune II 😜
Trying to figure out the timer #AtMega8 again got into thinking in terms of ``data == code'': it didn’t even occur to me that changing the interrupt vector on the fly is not so easy. A lot can be said about the Harvard architecture, and it must be said because it cannot be printed.
I woke from a dream where coders had to deal with a world where there were a finite number of operators and reserved words in the world and people had to take apart old programs and save them in files for later use - like you'd save screws and nuts and things in baby food jars to use on future projects.
Them: Why are you using a #AtMega8 in this decade?
Me: I don't think we can be friends.
Added a 200 millisecond delay after executing the page write command. This helped --- the temporary page buffer stopped spoiling. I don’t like this solution at all, and if the modern chips behave in the same way, then I'll return in search of a mistake, but so far they are not at hand.
Partial success. In brief: in the reference example of the program for writing to flash (p. 212 of the #AtMega8 datasheet) there is a line: ``sbci ZH, high(PAGESIZEB) ; not required for PAGESIZEB<=256'' That's a bullshit🤨
This instruction is needed regardless of page size. How scary to live if you can not believe the datasheets.
