C515C
Interrupt System
The C515C provides 17 interrupt sources with four priority levels. Seven interrupts can
be generated by the on-chip peripherals (timer 0, timer 1, timer 2, serial interface,
A/D converter, SSC interface, CAN controller), and ten interrupts may be triggered
externally (P1.5/T2EX, P3.2/INT0, P3.3/INT1, P1.4/INT2, P1.0/INT3, P1.1/INT4,
P1.2/INT5, P1.3/INT6, P7.0/INT7, P4.5/INT8). The wake-up from power-down mode
interrupt has a special functionality which allows to exit from the software power-down
mode by a short low pulse at pin P3.2/INT0.
In the C515C the 17 interrupt sources are combined to six groups of two or three interrupt
sources. Each interrupt group can be programmed to one of the four interrupt priority
levels.
