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.
Figure 21 shows the Interrupt Block Diagram.
