3.4 Modes of Operation
• Selects the chip operating mode:
– Master mode
– Single-chip mode
– Emulation mode
– Factory access slave test (FAST) mode for factory test only
• Selects external clock or phase-lock loop (PLL) mode with internal
or external reference
• Selects output pad strength
• Selects boot device
• Selects module configuration
• Selects bus monitor configuration
The CCM configures the chip for four modes of operation:
• Master mode
• Single-chip mode
• Emulation mode
• FAST mode for factory test only
The operating mode is determined at reset and cannot be changed
thereafter.
