NOTES:
1
All “open drain” outputs of the MPC5200 are actually regular three-state output drivers with the output data tied low
and the output enable controlled. Thus, unlike a true open drain, there is a current path from the external system to
the MPC5200 I/O power rail if the external signal is driven above the MPC5200 I/O power rail voltage.
