Cautions 1. Directly connect the IC (Internally Connected) pins to VSS0 or VSS1.
2. Connect the AVSS pin to VSS0.
Remarks 1. ××× indicates ROM code suffix.
2. If the microcontroller is used in an application where the noise generated from the microcontroller
must be suppressed, it is recommended that power be supplied to VDD0 and VDD1 from separate
sources, and that VSS0 and VSS1 be connected to separate group lines, to improve noise immunity.
