C509-L
Interrupt System
The C509-L provides 19 interrupt sources with four priority levels. 12 interrupts can be generated by
the on-chip peripherals and 7 interrupts may be triggered externally. In the C509-L the 19 interrupt
sources are combined to six groups of three or four interrupt sources. Each interrupt group can be
programmed to one of the four interrupt priority levels. Figure 30 to 33 give a general overview of
the interrupt sources and illustrate the interrupt request and control flags.
