Detailed Description
Contains several macros usable for making assertions.
Depending on the type of assertion (either static or at runtime), a failing assertion will trigger an error. For static assertion, this error will be shown at compile time and abort compilation. Runtime assertions will trigger a message containing details about the error occurred and will make the CPU die.

Handles a failed assertion.
This function will print a message containing further information about the failed assertion and stops the current CPU permanently.
- Note
- This function should never be called directly, but only via the macro
