Application Circuits
Note:
The resistance and capacitance for the reset circuit should be designed to ensure that VDD is stable and re-
mains within a valid range of the operating voltage before bringing RES high.
* Make the length of the wiring, which is connected to the RES pin as short as possible, to avoid noise
interference.
The following table shows the C1, C2 and R1 values corresponding to the different crystal values. (For refer-
ence only)

The function of the resistor R1 is to ensure that the oscillator will switch off should low voltage condi-
tions occur. Such a low voltage, as mentioned here, is one which is less than the lowest value of the
MCU operating voltage. Note however that if the LVR is enabled then R1 can be removed.
