I want to know if there is information available on the time delay >from arrival of a wakeup interrupt to actual processing start on a 16C84. I want to use my '84 as a code receiver and have it sleep between transmissions. Codes are sent at 1200 baud and I use a 1MHz resonator as clock source (configured as XT type). Is the wakeup time short enough and stable enough to not miss the first information bit? In the documentation they say that the time delay is 1024 clock cycles, but what about the time for the oscillator to start? Is this startup time temperature dependent? If so how much? I hope someone out there knows the answer to this one... :-) Cheers! Bo Berglund PaddelvŠgen 10, S-17545 JŠrfŠlla, Sweden e-mail: bo.berglund@mailbox.swipnet.se
