7.0 Power Saving Features
8.0 Interrupts
8.1 INTRODUCTION
Each device supports eight vectored interrupts. Interrupt
sources include Timer 0, Timer 1, EERAM Write Complete,
Port L Wakeup, Software Trap, MICROWIRE/PLUS, and Ex-
ternal 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 7 maskable inputs has a fixed arbitration ranking
and vector.
Figure 18 shows the Interrupt Block Diagram.
