The C868 provides 13 interrupt vectors with four priority levels. Nine interrupt requests
are generated by the on-chip peripherals (timer 0, timer 1, timer 2, serial channel, A/D
converter, and the capture/compare unit with 4 interrupts) and four interrupts may be
triggered externally.
The wake-up from power-down mode interrupt has a special functionality which allows
the software power-down mode to be terminated by a short negative pulse at pins
CCPOS0/T2/INT0/AN0 or P1.4/RxD.
The 13 interrupt sources are divided into six groups. Each group can be programmed to
one of the four interrupt priority levels. Additionally, 4 of these interrupt sources are
channeled from 7 Capture/Compare (CCU6) interrupt sources.
