5.3 Interrupt Request Sources in Internal Peripheral I/O
The Interrupt Controller receives as inputs the interrupt requests from MJT (multijunction timer), DMAC, serial I/O,
A-D converter, RTD and CAN. For details about these interrupts, see each section in which the relevant internal
peripheral I/O is described.

Note 1: ICU type of input source
• Edge-recognized: Interrupt requests are generated on a falling edge of the interrupt signal supplied to the ICU.
• Level-recognized: Interrupt requests are generated when the interrupt signal supplied to the ICU is held low. For
this type of interrupt, the ICU’s Interrupt Control Register IRQ bit cannot be set or cleared in software.
