9.0 Interrupts

9.1 INTRODUCTION

The device supports eight vectored interrupts. Interrupt

sources include Timer 1, Timer T0, Port L Wakeup, Software

Trap, MICROWIRE/PLUS, and External Input.

All interrupts force a branch to location 00FF Hex in program

memory. The VIS instruction may be used to vector to the

appropriate service routine from location 00FF Hex.

The Software trap has the highest priority while the default

VIS has the lowest priority.

Each of the six maskable inputs has a fixed arbitration

ranking and vector.
