Reset Operation
During the software watchdog reset period, all signals that can be are driven to a
high-impedance state; all those that cannot be are negated. When RSTO negates, bus
signals remain in a high-impedance state until the MCF5307 is granted the bus and the
ColdFire core begins the first bus cycle for reset exception processing.
