Section 9 Interrupt Controller (INTC)
9.1.2
Table 9.1 shows an example of the interrupt types. The INTC supports both the external interrupts
and on-chip module interrupts.
The external interrupts is the interrupt input from external pins, NMI, IRL, and IRQ.
The IRQ and IRL are assigned to the same pin in the SH7763. The pin function is selected
according to the system.
IRQ input can be selected as a level, or a rising or falling edge.

For example
IRL[7:4] pin = H'0 means
external pin input level is,
IRL[7] pin = Low
IRL[6] pin = Low
IRL[5] pin = Low
IRL[4] pin = Low
then priority level is,15
