an instruction to generate an exception is executed; and those that are generated by hardware, such as an
interrupt request signal from an external pin or peripheral function.
7.1 Overview
7.1.1
Exceptions
Exceptions have close relation to the CPU core. Refer to “Cortex-M3 Technical Reference Manual” if
There are two types of exceptions: those that are generated when some error condition occurs or when
the respective priority levels. When an exception occurs, the CPU stores the current state to the stack
and branches to the corresponding interrupt service routine (ISR). Upon completion of the ISR, the
information stored to the stack is automatically restored.
For detailed descriptions on each exception, refer to “Cortex-M3 Technical Reference Manual”.
This chapter describes features, types and handling of exceptions.
All exceptions are handled by the Nested Vectored Interrupt Controller (NVIC) in the CPU according to
An exception causes the CPU to stop the currently executing process and handle another process.
The following types of exceptions exist in the Cortex-M3.
