The H8/3064F-ZTAT and H8/3062F-ZTAT A-mask version 5 V operation models have a V
(internal step-down) pin, to which a 0.1 µF internal voltage stabilization capacitor must be
connected.
The method of connecting the external capacitor is shown in figure 1.6.
Do not connect the V
pins as usual.) Note that the V
