C515
Interrupt System
The C515 provides 12 interrupt sources with four priority levels. Five interrupts can be generated by
the on-chip peripherals (timer 0, timer 1, timer 2, A/D converter, and serial interface) and seven
interrupts may be triggered externally (P3.2/INT0, P3.3/INT1, P1.4/INT2, P1.0/INT3, P1.1/INT4,
P1.2/INT5, P1.3/INT6).
This chapter shows the interrupt structure, the interrupt vectors and the interrupt related special
function registers. Figure 15 and 16 give a general overview of the interrupt sources and illustrate
the request and the control flags which are described in the next sections.
