Preventing STOREs
The STORE function is disabled by holding HSB HIGH with a
driver capable of sourcing 30 mA at a V
because it has to overpower the internal pull down device. The
device drives HSB low for 20 ns at the onset of a STORE. When
the CY22E016L is connected for AutoStore operation (system
