FOperation notes

The reset circuits in the IC could fail to operate properly,

depending on the way the supply voltage rises when

power is applied. To avoid problems, we recommend ad-

ding a circuit to the HS pin, as shown in the diagram be-

low. (There is no need for this circuit, however, if the HS

pin momentarily goes HIGH by some other means, for

example, by CPU control.)
