32. If an SRAM write has not taken place since the last nonvolatile cycle, no AutoStore or Hardware STORE takes place.
33. On a Hardware STORE and AutoStore initiation, SRAM write operation continues to be enabled for time t
34. These parameters are guaranteed by design and are not tested.
35. Read and Write cycles are ignored during STORE, RECALL, and while V
36. During power-up and power-down, HSB glitches when HSB pin is pulled up through an external resistor.
