Output: Leave open.
KRREN When this pin is connected to VDD, the internal reset signal is
generated at the falling edge of the KRn pin in the STOP mode.
When this pin is connected to VSS, the internal reset signal is not
generated even if the falling edge of the KRn pin is detected in the
STOP mode.
IC Connect directly to VDD.
