• How should unused interrupt vectors be treated?
    • The occurrence of unused interrupt indicates an abnormal situation. We recommend fail-safe processing be executed, such as a reset by BRK instruction.
      The following shows an example.

      * Interrupt vector table
      static void int_NULL(void);

      #pragma INTERRUPT int_NULL 0x0C 1
      #pragma INTERRUPT int_NULL 0x0E 1

      * int_NULL
      static void int_NULL(void)
      #pragma asm
      mov psw, #02h
      #pragma endasm
