Note 3:
Note 4:
Note 5:
Using other than a 10 MHz crystal is not recommended because the crystal referred timing and frequency parameters will change
accordingly.
During this period, commands are not accepted by the chip. For detailed information see the Reset modes section.
The crystal oscillator start-up time strongly depends on the capacitance seen by the oscillator. Using low capacitance and low ESR
crystal is recommended. When designing the PCB layout keep the trace connecting to the crystal short to minimize stray
capacitance.
