Note:
(1)
RECALL signal has priority over STORE signal when both are applied at the same time.
(2)
STORE is inhibited when RECALL is active.
(3) The store operation is inhibited when VCC is below ≈ 3.0V.
(4) This parameter is tested initially and after a design or process change that affects the parameter.
