Driving outputs on initialization

Archiver

I seem to remember the BS2 documentation says all IO pins are set to
inputs on initialization. I need to hold the Enable pin high on a
74hc4514 decoder, until a HIGH # command can be given, to take a BS2 pin
high. I have put a 10k pullup on the Enable pin of the 74hc4514 to
accomplish this. I have not tested this and I am about ready to have
some boards made. Does this look like a proper solution, or does
someone have a better idea?

Thanks,
Dan Thames
