Interrupt System
The C505 provides 12 interrupt vectors with four priority levels. Five interrupt requests can be
generated by the on-chip peripherals (timer 0, timer 1, timer 2, serial interface, A/D converter). One
interrupt can be generated by the CAN controller (C505C and C505CA only) or by a software setting
and in this case the interrupt vector is the same. Six interrupts may be triggered externally (P3.2/
INT0, P3.3/INT1, P1.0/AN0/INT3/CC0, P1.1/AN1/INT4/CC1, P1.2/AN2/INT5/CC2, P1.3/AN3/INT6/
CC3). Additionally, the P1.5/AN5/T2EX can trigger an interrupt. 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 either pin P3.2/INT0 or the pin P4.1/RXDC.

control flags which are described in the next sections. Table 10 lists all interrupt sources with their
request flags and interrupt vectior addresses.
