We plan on using a GPS PPS signal that will be used to update the =
internal clock on each net burner (one for each application/sensor). One =
issue we are currently trying to resolve is how best to handle the PPS =
signal. The ISR can interface either with an internal register or =
hardware counter. Using the TIN0-3 inputs will interrupt an internal =
timer that can be used for the offset correction from the time received =
through the network.  Is there a way to access the TIN0-TIN3 pins on the =
Coldfire with this board?

(I did send a question to NB support but haven't heard back from them)

thanks,

Eric
