and, thus, did not remember RESET instead of !RESET.
High reset, typically, will be totem-pole driven when acting as an output and normally functioning as an input. Last I had multiple devices with high reet on a board, I used 1k resistors to a 'star point' to interconnect them. With CMOS I am sure a larger resistance would work as well, but the time of these in different states is so rare and short that I decided to play it safe. I DO know that this may backfire if onw device is actively pulling to reset and another is actively pulling not to reset, but that did never happen. Erik |
