/* 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.
