i reading code else wrote , confused how defined registers code goes this: uint32 gcro; unit32 ; 7u; i don't understand second line means. code repeats different named registers , uint32 ;7u; line again. understanding appreciated. in c language, unit32 ; 7u; not one, 2 unrelated expressions, since semi-colon separates them. depending on how uint32 defined, doesn't seem valid c code. defined typedef unsigned long uint32 , in case unit32 ; won't compile. 7u; valid c, though dummy line no effect. equivalent writing (unsigned int)7;
