Application Circuits
Note:
Rev. 1.50
It is recommended that a 100 F decoupling capacitor is placed between VSS and VDD.
The resistance and capacitance for reset circuit should be designed to ensure that the VDD is stable and re-
mains in a valid range of the operating voltage before bringing RES to high.
The following table shows the C value according to different crystal values. (For reference only)
