C505 / C505C
C505A / C505CA
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.

give a general overview of the interrupt sources and illustrate the request and the
control flags which are described in the next sections. Table 10 lists all interrupt sources with their
request flags and interrupt vectior addresses.
