Section 10 Interrupt Controller (INTC)
10.1.2
Table 10.1 shows an example of the interrupt types. The INTC supports both external interrupts
and on-chip 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 SH7780. 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.

Inverse of values on the input
pins (because the signals are
active low)
For example
IRL[7:4] pin = H'0 means the
external pin input levels are:
IRL[7] pin = Low
IRL[6] pin = Low
IRL[5] pin = Low
IRL[4] pin = Low
so the priority level is 15 (H'F)
(see table 10.11)
