The dd2 has a dedicated flipflop to do this but this dd3 seems to just use 2 of the 4 sections of a 74HC00 to act as a buffer to doubly invert and nothing more, and then that signal goes to a pin on the main micro with any de-bounce/divide by 2 function built in there, it would seem. I've only done partial circuit tracing so that may be wrong.

Did a better subcircuit determination Using one wasted, as paired-up, input to one of the SM 74HC00 gates , cutting just one pcb trace and added an R,a C and a D constructed a 0.4s monostable, pulse stretcher so now latching properly. It does not seem to have affected the hold mode option either. Fuller details eventually on repair2.htm file off URL below as latching failures seem quite common with DD2 and DD3 according to the archives
