/* Interrupt Matrix
|

|

* The Interrupt Matrix embedded in the ESP32C3 independently allocates

* peripheral interrupt sources to the CPUs’ peripheral interrupts.
|
||
* This configuration is highly flexible in order to meet many different
|

* needs.
|

|
||
* Features
|
||
* - Accepts 62 peripheral interrupt sources as input.
|
||
* - Generate 31 peripheral interrupts to CPU as output.
|
||
* - Queries current interrupt status of peripheral interrupt sources.
