If the device is in NORMAL or STOP mode, WDT initiates a System Reset at 
timeout if the
state of the
WDT to cause an interrupt, not a System Reset at timeout. The WDT status bit in the Reset
Status Register is set to signify that the reset was initiated by the WDT.
The RESET pin has a Schmitt-triggered input and an internal pull-up resistor. When the
RESET pin is asserted for a minimum of four system clock cycles, the device progresses
through the System Reset sequence. Because of the possible asynchronicity of the system
