Register 10: QEI Raw Interrupt Status (QEIRIS), offset 0x024
This register provides the current set of interrupt sources that are asserted, regardless of whether
they cause an interrupt to be asserted to the controller (this is set through the QEIINTEN register).
Bits set to 1 indicate the latched events that have occurred; a zero bit indicates that the event in
question has not occurred.
