Note 1) All voltage values are specified as VSS= VSSR= VSSL=0V.
Note 2) If the LSI is used on condition beyond the absolute maximum rating, the LSI may be destroyed. Using
LSI within electrical characteristics is strongly recommended for normal operation. Use beyond the
electrical characteristics conditions will cause malfunction and poor reliability.
Note 3) Decoupling capacitors should be connected between VDD-VSS, VDDR-VSSR and VDDL-VSSL due to the
stabilized operation.
