10.1: Fatal Error Default Handler

The _CPU_Fatal_halt routine is the default fatal error handler. This routine copies _error into a known place -- typically a stack location or a register, optionally disables interrupts, and halts/stops the CPU. It is prototyped as follows and is often implemented as a macro:

void _CPU_Fatal_halt(
    unsigned32 _error
);
