3.6 Program Enable (PE)
This pin allows the user to enable or disable the ability
to write data to the memory array. If the PE pin is tied
to VCC, the device can be programmed. If the PE pin is
tied to VSS, programming will be inhibited. PE is not
available on 93XX76A or 93XX76B. On those devices,
programming is always enabled. This pin cannot be
floated, it must be tied to VCC or VSS.
