Note: Interrupt flags must be cleared and then read back to confirm the clear before
exiting the ISR to avoid double interrupts.

Bit 0 – SQI SQI Interrupt Status Flag
Read value reflects the state of the interrupt flag. Do not use the interrupt flag and associated mask registers if the EIP already provides similar controls for its interrupts. This feature is design for interrupts created in the SIB or EIP which do not have mask or flag bits.
Write to ‘1’ to clear the flag.
