10.1.2 Interrupt Sources
Table 10.1 shows an example of the interrupt types. The INTC supports both external interrupts
and on-chip peripheral module interrupts.
External interrupts refer to the interrupts input through the external NMI, IRL, and IRQ pins.
The IRQ and IRL interrupts are assigned to the same pins in the SH7785. The pin functions are
selected to suit the system configuration.
Ether level-sense, or the rising or falling edge, can be selected for the detection of IRQ input.
