KRREN
When this pin is connected to V
DD
, internal reset signal is gener-
ated at the falling edge of the KRn pin in the STOP mode.
When this pin is connected to V
SS
, internal reset signal is not
generated even if the falling edge of KRn pin is detected in the
STOP mode.
IC
Connect directly to V
DD
.
