6.1 Features
6.2 Description
6.3 Interrupt sources
UM10360
User manual
The Nested Vectored Interrupt Controller (NVIC) is an integral part of the Cortex-M3. The
tight coupling to the CPU allows for low interrupt latency and efficient processing of late
arriving interrupts.
Refer to the Cortex-M3 User Guide
Table 50
may have one or more interrupt lines to the Vectored Interrupt Controller. Each line may
represent more than one interrupt source, as noted.
Exception numbers relate to where entries are stored in the exception vector table.
Interrupt numbers are used in some other contexts, such as software interrupts.
In addition, the NVIC handles the Non-Maskable Interrupt (NMI). In order for NMI to
operate from an external signal, the NMI function must be connected to the related device
pin (P2.10 / EINT0n / NMI). When connected, a logic 1 on the pin will cause the NMI to be
processed. For details, refer to the Cortex-M3 User Guide that is an appendix to this User
Manual.
