Nano 33 BLE: Software interrupts?

Is there any library available to configure software interrupts on the Arduino Nano 33 BLE?

All the information that I find on the web are for older micro-controllers. Thanks.

The Arduino Nano 33 BLE uses a Nordic nRF52840 microcontroller inside the u-blox NINA module. The processor of the nRF52840 is a ARM Cortex-M4 and runs mbedOS. Interrupt handling for Cortex-M processors are standardized in Cortex Microcontroller Software Interface Standard (CMSIS). The files are part of the Arduino board package.

Google for CMSIS SVC and mbedOS SVC on how to use them.

Thanks for the information.

I came across the following post Cannot get timer on the Nano 33 BLE working and found it very helpful.
