Register 4: Raw Interrupt Status (RIS), offset 0x050
This register indicates the status for system control raw interrupts. An interrupt is sent to the interrupt
controller if the corresponding bit in the Interrupt Mask Control (IMC) register is set. Writing a 1
to the corresponding bit in the Masked Interrupt Status and Clear (MISC) register clears an interrupt
status bit.
