... X5083 PRINCIPLES OF OPERATION Power On Reset Application of power to the X5083 activates a power on reset circuit. This circuit goes LOW at 1V and pulls the RESET pin active. This signal prevents the system microprocessor from starting to operate with insuffi- cient voltage or prior to stabilization of the oscillator. ...

... X5083 Write Enable Latch The device contains a Write Enable Latch. This latch must be SET before a Write Operation is initiated. The WREN instruction will set the latch and the WRDI instruction will reset the latch (Figure 7). This latch is automatically reset upon a power-up condition and after the completion of a valid Write Cycle ...
