#177931 - Brief Heavy or Not Responding to: ???'s previous message |
The presence of the brief heavy pullup in an MCU that is used on a board can present a quite different signal integrity issue from an MCU that does not have this characteristic when applied to the same circuit and layout topology. Of couse the nature of the attached circuit load (and possibly attached ribbon cable) can also vary the behavior of either type of MCU output.
