Interrupt Exception Processing Vectors Table
Table 6.2 lists interrupt sources and their vector numbers, vector table address offsets and interrupt
priorities.
Each interrupt source is allocated a different vector number and vector table address offset. Vector
table addresses are calculated from the vector numbers and address offsets. In interrupt exception
processing, the exception service routine start address is fetched from the vector table indicated by
the vector table address. For the details of calculation of vector table address, see table 5.4,
Calculating Exception Processing Vector Table Addresses in the section 5 Exception Processing.
IRQ interrupts and on-chip peripheral module interrupt priorities can be set freely between 0 and
15 for each pin or module by setting interrupt priority registers A, D to I, K (IPRA, IPRD to IPRI,
IPRK). However, the smaller vector number has interrupt source, the higher priority ranking is
assigned among two or more interrupt sources specified by the same IPR, and the priority ranking
cannot be changed. A power-on reset assigns priority level 0 to IRQ interrupts and on-chip
peripheral module interrupts. If the same priority level is assigned to two or more interrupt sources
and interrupts from those sources occur simultaneously, they are processed by the default priority
order indicated in table 6.2.
