Hello,

Traps interrupt the current execution like standard interrupts do. However, trap functions offer the possibility to bypass the interrupt system prioritization process in cases where immediate system reaction is required. Trap functions are not maskable and always have priority over interrupt requests on any priority level.

The ST10 provides two kinds of traps: software and hardware traps. Have a look at the ST10x167 user's manual (INTERRUPT AND TRAP FUNCTIONS section), this will help you.
