Event Manager
The NVIC also contains a software-configurable interrupt prioritization mechanism. The Reset, NMI, and Hard
Fault exceptions, in that order, are always the highest priority, and are not software-configurable. All other
exceptions can be assigned a 5-bit priority number, with low values representing higher priority. If any
exceptions have the same software-configurable priority, then the NVIC uses the hardware-defined priority.
The hardware-defined priority number is the same as the position of the exception in the exception table. For
example, if IRQA and IRQB both fire at the same time and have the same software-defined priority, the NVIC
handles IRQA, with priority number 28, first because it has a higher hardware priority than IRQB with priority
number 29.
The top-level interrupts are controlled through five ARM
INT_CFGCLR, INT_PENDSET, INT_PENDCLR, and INT_ACTIVE. Writing 0 into any bit in any of these five register
is ineffective.
INT_PENDSET and INT_PENDCLR set and clear a simple latch; INT_CFGSET and INT_CFGCLR set and clear a
mask on the output of the latch. Interrupts may be pended and cleared at any time, but any pended interrupt
will not be taken unless the corresponding mask (INT_CFGSET) is set, which allows that interrupt to
propagate. If an INT_CFGSET bit is set and the corresponding INT_PENDSET bit is set, then the interrupt will
propagate and be taken. If INT_CFGSET is set after INT_PENDSET is set, then the interrupt will also propagate
and be taken. Interrupt flags (signals) from the top-level interrupts are level-sensitive.
The second-level interrupt registers, which provide control of the second-level Event Manager peripheral
interrupts, are described in the Event Manager section.
For further information on the NVIC and ARM
Technical Reference Manual and the ARM ARMv7-M Architecture Reference Manual.
While the standard ARM
the CPU, the Ember proprietary Event Manager provides second-level interrupts. The Event Manager takes a
large variety of hardware interrupt sources from the peripherals and merges them into a smaller group of
interrupts in the NVIC. Effectively, all second-level interrupts from a peripheral are “OR’d” together into a
single interrupt in the NVIC. In addition, the Event Manager provides missed indicators for the top-level
peripheral interrupts with the register INT_MISS.
The description of each peripheral’s interrupt configuration and flag registers can be found in the chapters of
this datasheet describing each peripheral. Figure 11-1 shows the Peripheral Interrupts Block Diagram.
INT_CFGSET - Writing 1 to a bit in INT_CFGSET enables that top-level interrupt.
INT_CFGCLR - Writing 1 to a bit in INT_CFGCLR disables that top-level interrupt.
INT_PENDSET - Writing 1 to a bit in INT_PENDSET triggers that top-level interrupt.
INT_PENDCLR - Writing 1 to a bit in INT_PENDCLR clears that top-level interrupt.
INT_ACTIVE cannot be written to and is used for indicating which interrupts are currently active.
