1 100 nF capacitance needs to be provided between V
DDA/VSSA pair.
2 Full functionality cannot be guaranteed when voltage drops below 4.5 V. In particular, I/O DC and ADC electrical
characteristics may not be guaranteed below 4.5 V during the voltage drop sequence.
3 200 F capacitance must be connected between V
DDR and VSS12. This is required because of sharp surge due to
external ballast.
4 V
DD12 cannot be used to drive any external component.
5 Each V
DD12/VSS12 supply pair should have a 10 F capacitor. Absolute combined maximum capacitance is 40 F.
6 V
DD refers collectively to I/O voltage supplies, i.e., VDDE_A, VDDE_B, VDDE_C, VDDE_E, VDDMA, VDDMB and VDDMC.

9 V
DDE_C should be the same as VDDA with a 100 mV variation, i.e., VDDE_C = VDDA ±100 mV.
