2. When reading pin states using the port D register (PORTD), after accessing
Communication Operation.
EXMDLSTP (address range: H'FFFF40 to H'FFFF5F), you must perform a dummy read
to the external address space (such as H'FFEF00 to H'FF7FF) outside the range
H'FFFF40 to H'FFFF5F before reading PORTD.

These bits are always read as an undefined value and
cannot be modified.
RTC Module Stop
0: Cancels the RTC module stop.
1: Sets the RTC module stop.
USB Module Stop 1
0: Cancels the stop state of the USB module partly.
1: Places the USB module completely in the stop state.
A clock is provided for the USB module partly. After
this bit has been cleared, only the UCTLR and
UIER3 registers in the USB module can be
accessed. To access the other registers, clear the
MSTPB0 bit in MSTPCRB to 0.
The clocks in the USB module stop operation
completely. However, register values in the USB
module are maintained.
