Electrical characteristics
1 _{100 nF capacitance needs to be provided between VDDA/VSSA pair.}
2 _{10 F capacitance must be connected between VDDR and VSS12 because of a sharp surge due to external ballast.}
3 _{VDD12 cannot be used to drive any external component.}
4 _{Each VDD12/VSS12 supply pair should have a 10 F capacitor. Absolute combined maximum capacitance is 40 F. Preferably,}
all the VDD12 supply pads should be shorted and then connected to a 4  10 F capacitance. This is to ensure the ESR of
external capacitance does not exceed 0.2 . A 100 nF capacitor must be placed close to the pin.
5 _{VDD refers collectively to I/O voltage supplies, i.e., VDDE_A, VDDE_B, VDD_DR, and VDDM.}
6 _{100 nF capacitance needs to be provided between each VDD/VSS pair. VDDmin value for is 3 V for VDDE_A & VDDM as well}
as for VDDE_B, while it is 1.62 V for VDD_DR. VDD max value is 3.6 V for VDDE_A & VDDM as well as for VDDE_B &
VDD_DR.
7 _{Full electrical specification cannot be guaranteed when voltage drops below 3.0V. In particular, ADC electrical characteristics}
and I/O’s DC electrical specification may not be guaranteed.
When voltage drops below V_LVDHVL device is reset.
8 _{VSS refers collectively to I/O voltage supply grounds, i.e., VSSE_A, VSS, and VSSM unless otherwise noted.}
9 _{VDDE_A should not be less than VDDA.}
10 _{Guaranteed by device validation.}
