via a resistor.
Output: Leave open.
KRREN When this pin is connected to V DD , the internal reset signal is
generated at the falling edge of the KRn pin in the STOP mode.
When this pin is connected to V SS , 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 V DD .
