Figure 3-8. OSC and PLL Block Diagram
The on-chip oscillator circuit enables a crystal/resonator to be attached to the 280x devices using the X1
and X2 pins. If the on-chip oscillator is not used, an external oscillator can be used in either one of the
following configurations:
1. A 3.3-V external oscillator can be directly connected to the XCLKIN pin. The X2 pin should be left
unconnected and the X1 pin tied low. The logic-high level in this case should not exceed V
