20 pF
using crystal mode, the system clock frequency is programmable (using the W, X, and Y
bits in the SYNCR) over the range specified in Section 11 Electrical Characteristics
(see Table 4-2.).
A separate power pin (V
the device powered down and to provide increased noise immunity for the clock circuits.
The source for V
capacitors placed as close as possible to the V
frequency. Figure 4-4 shows typical values for the bypass and PLL external capacitors.
The crystal manufacturer's documentation should be consulted for specific
recommendations for external components.
