Chip Configuration Module (CCM)
9.1

Introduction

The chip configuration module (CCM) controls the chip configuration for the device.
9.1.1 Block Diagram
9.1.2 Features
The CCM performs the following operations:
• Selects the chip operating mode
• Selects external clock or phase-lock loop (PLL) mode with internal or external reference
• Selects output pad drive strength
• Selects boot device and data port size
• Selects bus monitor configuration
• Selects low-power configuration
9.1.3 Modes of Operation
The only chip operating mode available on this device is master mode. In master mode, the ColdFire core
can access external memories and peripherals.The external bus consists of a 32-bit data bus and 24 address
