Q&A No.: QAH8S-049
Category: Power-Down State
Subject: Hardware Standby Mode at Power-On
Question
How can hardware standby mode be entered at power-on?
Answer
Drive the STBY pin low at power-on.
Note: The mode pins (MD2 to MD0) must be set to the prescribed input state at this time.
(In the H8S/2655 Series, at least one of pins MD2 to MD0 should be driven high, and one
of modes 1 to 7 must be selected as the MCU operating mode.)
