MCF5206e Integrated ColdFire® Microprocessor Product Brief

MOTOROLA

MCF5206e Overview

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. The interface is

common to all ColdFire-based processors and allows emulator support across the entire ColdFire family.
