Sep 30, 2010
When a low level is input to the RESET pin, the system is reset, and each hardware unit is initialized.
When the level of the RESET pin is changed from low to high, the reset status is released.
Note When the power is turned on, the following pin may output an undefined level temporarily, even during reset.
Caution The OCDM register is initialized by the RESET pin input. Therefore, note with caution that, if a high
