CHAPTER 16 RESET FUNCTION
User’s Manual U15104EJ2V0UD
Cautions 1. For an external reset, input a low level for 10
µ
s or more to the RESET pin.
2. During reset input, system clock oscillation remains stopped.
3. When the STOP mode is released by RESET input, the STOP mode register contents are held
during reset input. However, the I/O port pin becomes high-impedance. Output dedicated
port pin (P130 to P132) becomes low level regardless of the previous status.
