Interrupt Reason Flag register.
Each bit of this register is interrupt report flag of each
interrupt. “1” means interrupt is generated and “0”
means not generated. BIT writes “1” to the bit of each
interrupt when generates interrupt request and host
may acknowledge which interrupt is generated by
reading this register at interrupt service routine. Host is
responsible for resetting this register to “0” for next
interrupt
The interrupt matching of each bit field is same with
IntEnable register.
