mbed_official 579:53297373a894 78 *
mbed_official 579:53297373a894 79 * There are no prerequisites for this module.
mbed_official 579:53297373a894 80 *
mbed_official 579:53297373a894 81 *
mbed_official 579:53297373a894 82 * \section asfdoc_sam0_system_interrupt_module_overview Module Overview
mbed_official 579:53297373a894 83 *
mbed_official 579:53297373a894 84 * The ARM&reg; Cortex&reg; M0+ core contains an interrupt and exception vector table, which
mbed_official 579:53297373a894 85 * can be used to configure the device's interrupt handlers; individual
mbed_official 579:53297373a894 86 * interrupts and exceptions can be enabled and disabled, as well as configured
mbed_official 579:53297373a894 87 * with a variable priority.
mbed_official 579:53297373a894 88 *
mbed_official 579:53297373a894 89 * This driver provides a set of wrappers around the core interrupt functions,
mbed_official 579:53297373a894 90 * to expose a simple API for the management of global and individual interrupts
mbed_official 579:53297373a894 91 * within the device.
mbed_official 579:53297373a894 92 *
mbed_official 579:53297373a894 93 * \subsection asfdoc_sam0_system_interrupt_module_overview_criticalsec Critical Sections
mbed_official 579:53297373a894 94 * In some applications it is important to ensure that no interrupts may be
mbed_official 579:53297373a894 95 * executed by the system whilst a critical portion of code is being run; for
mbed_official 579:53297373a894 96 * example, a buffer may be copied from one context to another - during which
mbed_official 579:53297373a894 97 * interrupts must be disabled to avoid corruption of the source buffer contents
mbed_official 579:53297373a894 98 * until the copy has completed. This driver provides a basic API to enter and
mbed_official 579:53297373a894 99 * exit nested critical sections, so that global interrupts can be kept disabled
mbed_official 579:53297373a894 100 * for as long as necessary to complete a critical application code section.
mbed_official 579:53297373a894 101 *
mbed_official 579:53297373a894 102 * \subsection asfdoc_sam0_system_interrupt_module_overview_softints Software Interrupts
mbed_official 579:53297373a894 103 * For some applications, it may be desirable to raise a module or core
mbed_official 579:53297373a894 104 * interrupt via software. For this reason, a set of APIs to set an interrupt or
mbed_official 579:53297373a894 105 * exception as pending are provided to the user application.
mbed_official 579:53297373a894 106 *
mbed_official 579:53297373a894 107 * \section asfdoc_sam0_system_interrupt_special_considerations Special Considerations
mbed_official 579:53297373a894 108 *
mbed_official 579:53297373a894 109 * Interrupts from peripherals in the SAM devices are on a per-module basis;
mbed_official 579:53297373a894 110 * an interrupt raised from any source within a module will cause a single,
mbed_official 579:53297373a894 111 * module-common handler to execute. It is the user application or driver's
mbed_official 579:53297373a894 112 * responsibility to de-multiplex the module-common interrupt to determine the
mbed_official 579:53297373a894 113 * exact interrupt cause.
mbed_official 579:53297373a894 114 *
