Application Circuits
RC Oscillator for Multiple I/O Applications
Crystal or Ceramic Resonator for Multiple I/O
Applications
Note:
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.
