Since GCC 10, the compiler defaults to -fno-common, thus variables with multiple tentative definitions result in linker errors. We've (me and @MrMoDDoM) extern-ed the shared variables to fix the issue. Also, when I implemented ISR sharing, somehow I forgot about a function which was shared as well, so I fixed that mistake and added a couple of comments on how shared function calls work.
