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.
