SYSTEM INTERRUPT STATUS REGISTER

Device Address: 0x1E; Register Address: 0x0010, Reset: 0x1000, Name: CRSM_IRQ_STATUS

This address can be used to check which interrupt requests have been triggered since the last time it was read. Each bit goes high when

the associated event occurs and then latches high until it is unlatched by reading. The bits of CRSM_IRQ_STATUS go high even when the

associated interrupts are not enabled. A reserved interrupt being triggered indicates a system error, which requires a hardware reset.
