Note:
1. tSYS=1/fSYS
2. *For fERC, as the resistor tolerance will influence the frequency a precision resistor is recommended.
3. To maintain the accuracy of the internal HIRC oscillator frequency, a 0.1mF decoupling capacitor should
be connected between VDD and VSS and located as close to the device as possible.
