Section 9 Interrupt Controller (INTC)
Interrupt priorities should be determined by setting a value from H'F to H'1 to each 4-bit field. If
the value is larger, the priority is higher. When the value of H'0 is set to a field, a corresponding
interrupt is masked (initial value).
9.3.4
INTREQ is a 32-bit readable and writable with conditions register that indicates which IRQ [n] (n
= 0 to 7) interrupt is requested to the INTC.
Even if interrupts are masked by INTPRI and INTMSK0, the INTREQ bits are not affected.
