4.2.1 Write Time When no Erase is Required

When no erase is required, the write time is fairly constant at about 290 µs per word. There are four control words for each dataset. The time to write a dataset with four words of data is shown in Figure 4-1 from markers A to D and is 2.4 ms. Half the time is for writing the control words, the other half for writing the data.
