state of the WDI pin. This is effective when the watchdog function is not required, for example, during data loading to the
CPU. The WDI input is internally driven through a buffer (LOGIC) and series resistor (R
showed in the block diagrams of page 4 and 5. The WDI input is designed for minimizing the input current by placing the
series resistor (R
three-state device multiplied by the resistance value of the series resistor (RWD) when the three-state device is in the state
of high impedance. The voltage level must be reaching the threshold level of the WD so that a three-state device with small
leakage current should be selected.
When these series is used, external parts such as the three-state device is not required.
The other series is available in the name of XC6121~XC6124 with the ON/OFF control pin for the watchdog function.
