... When WP is held high, all functions, including non vol- atile writes operate normally. WP going low while still low will interrupt a write to the X5043/45. If the RESET/RESET internal write cycle has already been initiated, WP SCK going low will have no affect on a write. ...

... X5043/X5045 PRINCIPLES OF OPERATION Power On Reset Application of power to the X5043/X5045 activates a Power On Reset Circuit. This circuit pulls the RESET/ RESET pin active. RESET/RESET prevents the sys- tem microprocessor from starting to operate with insuf- ficient voltage or prior to stabilization of the oscillator. When V exceeds the device V ...
