Interrupt Status Preserve and Clear Registers. The interrupt status bits are set
when the corresponding events occur in the MAC. If the corresponding
interrupt enable bit is set in the interrupt enable register, an interrupt signal will
be generated.
Interrupt status is available at two different offsets: Interrupt Status Preserve
and Interrupt Status Clear. Both offsets are a read of the same storage.
Reading the Interrupt Status register Preserve has no effect on the status in
the register, but writing a 1 to a location in this register clears the status bit,
writing a zero has no effect. Reading the Interrupt Status Clear register clears
all the bits in the register that are accessed as defined by the AHB HSIZE
signal. Therefore a routine which will handle all reported status may read via
the Interrupt Status Clear thereby saving a write operation.

Reserved. Unknown During Read.
Remote Wake-up Interrupt. The remote wake status is set
when a remote wake-up frame is received, and the
RemoteWakeEn (RXCtl) is set. A remote wake-up frame
must pass the receive destination address filter and have
a contiguous sequence of 6 bytes of FFh followed by 8
repetitions of the Individual Address and be a legal frame
(legal length and good CRC).
