5.2 Interrupt Sources of Internal Peripheral I/Os

The interrupt controller receives as its inputs the interrupt requests from MJT (multijunction timer),
DMAC, serial I/O, A-D converter, RTD, and CAN. For details about these interrupts, refer to each
section in which the relevant internal peripheral I/O is described.

Note: ICU type of input source
• Edge-recognized: Interrupt requests are generated on a falling edge of the interrupt signal applied to
• Level-recognized: Interrupt requests are generated when the interrupt signal applied to the ICU is
