Recommended Connecting Method

Input state : Independently connect to VSS or VDD via a resistor.

Output state: Leave open.

Connect to VDD.

Input state : Independently connect to VSS or VDD via a resistor.

Output state: Leave open.

When this pin is connected to VDD, internal reset signal is gener-

ated at the falling edge of the KRn pin in the STOP mode.

When this pin is connected to VSS, internal reset signal is not

generated even if the falling edge of KRn pin is detected in the

STOP mode.

Connect directly to VDD.
