· Location 008H

This vector is used by the external interrupt 1. If the external interrupt pin receives an active edge,

the program will jump to this location and begin execution if the external interrupt is enabled and the

stack is not full.

· Location 00CH

This internal vector is used by the Timer/Event Counter 0. If a Timer/Event Counter 0 overflow

occurs, the program will jump to this location and begin execution if the timer/event counter

interrupt is enabled and the stack is not full.

· Location 010H

This internal vector is used by the Timer/Event Counter 1. If a Timer/Event Counter 1 overflow

occurs, the program will jump to this location and begin execution if the timer/event counter

interrupt is enabled and the stack is not full.

· Location 014H

This internal vector is used by the SPI/I

2C interrupt. When either an SPI or I2C bus, dependent upon

which one is selected, requires data transfer, the program will jump to this location and begin

execution if the SPI/I

2C interrupt is enabled and the stack is not full.

· Location 018H

This internal vector is used by the Multi-function Interrupt. When the Time Base overflows, the A/D

converter completes its conversion process, an active edge appears on the External Peripheral

interrupt pin, a Comparator output interrupt, an EEPROM Write or Read cycle ends interrupt, or a

LVD detection interrupt, the program will jump to this location and begin execution if the relevant

interrupt is enabled and the stack is not full.
