/* 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.
