5 / 12 page STK10C48 March 2006 5 Document Control # ML0002 rev 0.2 MODE SELECTION Note k: An automatic RECALL takes place at power up, starting when VCC exceeds 4.25V and taking tRESTORE. STORE CYCLES #1 & #2 (VCC = 5.0V ± 10%) Note l: Measured with W and NE both returned high, and G returned low. STORE cycles are inhibited below 4.0V. Note m: Once tWC has been satisfied by NE, G, W and E, the STORE cycle is completed automatically. Any of NE, G, W or E may be used to terminate the STORE initiation cycle. Note n: If E is low for any period of time in which W is high while G and NE are low, then a RECALL cycle may be initiated.
