... Note q: The six consecutive addresses must be in the order listed. W must be high during all six consecutive cycles to enable a nonvolatile cycle. Note r: While there are 20 address lines on the STK14EE8, only the lower 16 are used to control software modes Note s: I/O state depends on the state of G.

... I/O lines left low, internal circuitry will turn off the output buffers t low. AutoStore OPERATION The STK14EE8 stores data to nvSRAM using one of three storage operations. These three operations are Hardware Store (activated by HSB), Software Store (activated by an address sequence), and determine which of AutoStore (on power down) ...

... HSB is driven low or when V below V are given time to complete before the switch STORE operation is initiated. After AUTOSTORE or HSB goes low, the STK14EE8 will continue to allow SRAM operations for t .

... STORE and WRITE operations. The low-volt- age condition is detected when V If the STK14EE8 WRITE mode (both E and W low) at power-up, after a RECALL, or after a STORE, the WRITE will be inhibited until a negative transition detected. This protects against inadvertent writes during power up or brown out conditions ...
