+  The {IDF_TARGET_NAME} has one core, with 28 external asynchronous interrupts. Each interrupt has a programmable priority level. In addition, there are also 4 core local interrupt sources (CLINT). See *{IDF_TARGET_NAME} Technical Reference Manual* [`PDF <{IDF_TARGET_TRM_EN_URL}#riscvcpu>`__] for more details.

 Because there are more interrupt sources than interrupts, sometimes it makes sense to share an interrupt in multiple drivers. The :cpp:func:`esp_intr_alloc` abstraction exists to hide all these implementation details.
 
 A driver can allocate an interrupt for a certain peripheral by calling :cpp:func:`esp_intr_alloc` (or :cpp:func:`esp_intr_alloc_intrstatus`). It can use the flags passed to this function to set the type of interrupt allocated, specifying a particular level or trigger method. The interrupt allocation code will then find an applicable interrupt, use the interrupt mux to hook it up to the peripheral, and install the given interrupt handler and ISR to it.
