Register 11: QEI Interrupt Status and Clear (QEIISC), offset 0x028
This register provides the current set of interrupt sources that are asserted to the controller. Bits set
to 1 indicate the latched events that have occurred; a zero bit indicates that the event in question
has not occurred. This is a R/W1C register; writing a 1 to a bit position clears the corresponding
interrupt reason.

DescriptionResetTypeNameBit/Field
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
