Section 31 Electrical Characteristics
31.6 Usage Note
Mount a multilayer ceramic capacitor between a pair of pins PVcc and PVss, VccR and VssR, or
PLLVcc and PLLVss as a bypass capacitor. These capacitors must be placed as close as the power
supply pins of the LSI. Also, a capacitor must be connected between the VCL and VSS pins to
stabilize the power supply voltage that is internally lowered.
Figure 31.49 is an example of externally allocated capacitors.
