CHAPTER 6 INTERRUPT AND TEST FUNCTIONS
6.2 TYPES OF INTERRUPT SOURCES AND VECTOR TABLESTable 6-1 lists the types of interrupt sources, and Figure 6-2 shows vector tables.Table 6-1. Interrupt Sources
Interrupt source signal In/out Interrupt Vectored interrupt request
priorityNote (vector table address)
INTBT Reference time interval signal from In 1 VRQ1 (0002H)
basic interval timer/wactchdog timer
INT4 Detection of both rising and falling Out
edges
INT0 Rising/falling edge Out 2 VRQ2 (0004H)
INT1 detection specification Out 3 VRQ3 (0006H)
INTCSI Serial data transfer completion signal In 4 VRQ4 (0008H)
INTT0 Match signal between the count In 5 VRQ5 (000AH)
register of timer/event counter 0
and modulo register
INTT1 Match signal between the count In 6 VRQ6 (000CH)
register of timer counter 1
and modulo register
Note The interrupt priority is used to determine the priority when two or more interrupts aresimultaneously generated.Figure 6-2. Interrupt Vector Table
