/* 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.

* 26 can be mapped to peripheral interrupts:
|

*
|
||
* Level triggered peripherals (21 total):
|

* 0-5, 8-9, 12-13, 17-18 - Priority 1
|

|
||
* NMI (1 total):
|
||
* 14 - NMI
|
||
*
|
||
* CPU peripheral interrupts can be a assigned to a CPU interrupt using the
|
||
* PRO_*_MAP_REG or APP_*_MAP_REG. There are a pair of these registers for
|
||
* each peripheral source. Multiple peripheral interrupt sources can be
|
||
* mapped to the same.
|

*
|
||
* The remaining, five, internal CPU interrupts are:
|
||
*
|
||
* 6 Timer0 - Priority 1
|
||
* 7 Software - Priority 1
|
||
* 11 Profiling - Priority 3
|

* 15 Timer1 - Priority 3
|
||
* 16 Timer2 - Priority 5
|
||
* 29 Software - Priority 3

* A peripheral interrupt can be disabled
