6.1.3 Modes of Operation
• Run mode
This is the basic mode of operation.
• Wait mode
In wait mode, the XINT module is frozen. It is however capable of either waking up the CPU if an
interrupt occurs or waking up the XGATE if an XGATE request occurs. Please refer to
Section 6.5.3, “Wake Up from Stop or Wait Mode” for details.
• Stop Mode
In stop mode, the XINT module is frozen. It is however capable of either waking up the CPU if an
interrupt occurs or waking up the XGATE if an XGATE request occurs. Please refer to
Section 6.5.3, “Wake Up from Stop or Wait Mode” for details.
• Freeze mode (BDM active)
In freeze mode (BDM active), the interrupt vector base register is overridden internally. Please
refer to Section 6.3.2.1, “Interrupt Vector Base Register (IVBR)” for details.
