separate input and output signals. For system protection, the processor includes a
programmable 16-bit software watchdog timer and several bus monitors. In addition,
common system functions such as chip selects, interrupt control, bus arbitration, and IEEE
1149.1 Test (JTAG) support are included.
A sophisticated debug interface supports both background-debug mode and real-time trace.
This interface is common to all ColdFire processors and allows common emulator support
across the entire ColdFire Family.
1.2 MCF5206E FEATURES
