... PRINCIPLES OF OPERATION Power-on Reset Application of power to the X5323/X5325 activates a power-on reset circuit. This circuit goes active at about 1V and pulls the RESET/RESET pin active. This signal prevents the system microprocessor from starting to operate with insufficient voltage or prior to stabilization of the oscillator. As long as RESET/RESET pin is active, the device will not respond to any Read/Write instruction ...

... X 7 X5323, X5325 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 3). This latch is automatically reset upon a power-up condition and after the completion of a valid write cycle. ™ ...
