82. It is important to get the correct ADC conversion result that the wiring resistance is accurate. Pay attention to keeping low noise.

It is recommended that the ceramic capacitor of the high frequency type to be used as a decoupling capacitor between AVDDADC and

AVSSADC.

Place the capacitor close to the terminal of LSI as much as possible so that the wiring length may be short as much as possible.

83. When the terminal VR is prepared (Package Code = “RA”, etc), the ADC conversion speed (operation clock frequency) is different

depending on the value of the capacitor used. Confirm specs of ADC.

84. VRH and AVddADC, VRL and AVssADC are connected in the package (Package Code = “TA”, “XA”, “XB”, “XC”, “XD”, etc). VR terminal

is open in the package.
