4.3 Functional Description
4.3.1 Interrupt Operation
2010-09-06 - d0001_Rev1.00
• Unaligned data storage and access
• Integrated power modes
• Optimized for low latency, nested interrupts
For a full functional description of the ARM Cortex-M3 implementation in the EFM32G family, the reader
is referred to the EFM32G Cortex-M3 Reference Manual.
Figure 4.1. Interrupt Operation
The EFM32G devices have up to 31 interrupt request lines (IRQ) which are connected to the Cortex-
M3. Each of these lines (shown in Table 4.1 (p. 12) ) is connected to one or more interrupt flags
in one or more modules. The interrupt flags are set by hardware on an interrupt condition. It is also
possible to set/clear the interrupt flags through the IFS/IFC registers. Each interrupt flag is then qualified
with its own interrupt enable bit (IEN register), before being OR'ed with the other interrupt flags to
generate the IRQ. A high IRQ line will set the corresponding pending bit (can also be set/cleared with
the SETPEND/CLRPEND bits in ISPR0/ICPR0) in the Cortex-M3 NVIC. The pending bit is then qualified
with a an enable bit (set/cleared with SETENA/CLRENA bits in ISER0/ICER0) before generating an
interrupt request to the core. Figure 4.1 (p. 11) illustrates the interrupt system. For more information
on how the interrupts are handled inside the Cortex-M3, the reader is referred to the EFM32G Cortex-
M3 Reference Manual.
Module
• Continuous storage of data requiring different byte lengths
• Data access in a single core access cycle
• Sleep Now mode for immediate transfer to low power state
• Sleep on Exit mode for entry into low power state after the servicing of an interrupt
• Ability to extend power savings to other system components
