/* Interrupt Matrix
|
||||
*
|
||||
* The Interrupt Matrix embedded in the ESP32 independently allocates
|
||||
* peripheral interrupt sources to the two CPUs’ peripheral interrupts. This
|
||||
* configuration is highly flexible in order to meet many different needs.
|
||||
*
|
||||
* Features
|
||||
* - Accepts 71 peripheral interrupt sources as input.
|
||||
* - Generates 26 peripheral interrupt sources per CPU as output (52 total).
|
||||
* - CPU NMI Interrupt Mask.
|
||||
* - Queries current interrupt status of peripheral interrupt sources.
|
||||
*
|
||||
* Peripheral Interrupt Source
|
||||
*
|
||||
* ESP32 has 71 peripheral interrupt sources in total. 67 of 71 ESP32
|
||||
* peripheral interrupt sources can be allocated to either CPU. The four
|
||||
* remaining peripheral interrupt sources are CPU-specific, two per CPU.
|
||||
*
|
||||
* - GPIO_INTERRUPT_PRO and GPIO_INTERRUPT_PRO_NMI can only be allocated to
|
||||
* PRO_CPU.
|
||||
* - GPIO_INTERRUPT_APP and GPIO_INTERRUPT_APP_NMI can only be allocated to
|
||||
* APP_CPU.
|
||||
*
|
||||
* As a result, PRO_CPU and APP_CPU each have 69 peripheral interrupt
|
||||
* sources.
