INTERRUPT SOURCES

Table 54 lists the interrupt sources for each peripheral function. Each peripheral device has one interrupt line connected to the
Vectored Interrupt Controller, but may have several internal interrupt flags. Individual interrupt flags may also represent more
than one interrupt source.
