Interrupt Source and Vector
Each interrupt event source has an associated interrupt vector address for the interrupt
node it belongs to. This vector is accessed to service the corresponding interrupt node
request. The interrupt service of each interrupt source can be individually enabled or
disabled via an enable bit. The assignment of the XC878 interrupt sources to the
interrupt vector address and the corresponding interrupt node enable bits are
summarized in Table 21.
