7.4. interrupt-factor Indicate Register/interrupt-mask Setting Register
interrupt-factor indicate register is the register that indicates interrupt reported by this LSI.
Refer to “Chapter 10 Interrupt” for measure against and details of each Bit and interrupt factor.
interrupt-mask setting register is the register that controls mask of each interrupt factor generated by this LSI.

1 Mask interrupt factors.
Interrupt factors masked by setting of this register are neither stored in interrupt
indicate register nor assert INT signal.
