As an alternative to using the RESET signal, PEN can be held low during Poweron Reset while SCK is set to “0”. In this case, only the PEN value at Power-on Reset is important. If the programmer cannot guarantee that SCK is held low during power-up, the PEN method cannot be used. The device must be powered down in order to commence normal operation when using this method.
