5.5 Interrupt sources
Tabl e 5 7 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.
