It sounds like a stupid question but I could not find in Coldfire V1 documentation any reference to schmitt-trigger inputs. In fact the word schmitt is not found at all. I'd like to save some schmitt ports...
Thanks for any hints,
Check the Vih and Vil figures, and Table 10 also gives:
Table 10: "DC Characteristics".
Input hysteresis; all digital inputs Vhys: 0.06 x Vdd
So now we know Freescale uses the keyword "Hysteresis", search for that and find within the first few pages:
1.3.1 Feature List
• Input/Output — 66 GPIOs — Eight keyboard interrupt pins with selectable polarity — Hysteresis and configurable pull-up device on all input pins; configurable slew rate and drive strength on all output pins
I owe U some beers.
