Figure 47. Typical Connection Diagram (Serial Mode)
Notes:
- For setting of XTL0 and XTL1, refer the Table 3.
- “C” depends on the crystal.
- AVSS and DVSS must be connected the same ground plane.
- Digital signals, especially clocks, should be kept away from the R pin in order to avoid an effect to the clock
jitter performance.
