In order to check if programmed "0" cells are within the specified range, the serial command for margin test must
be sent to the E²PROM control register with the V
out again. The E²PROM content must be equal to the requested content (refer to
Figure 33
Figure 34
The routine described above ensures that the programmed cells are inside the specified range. To optimize the
programming tool it is recommended to do a more detailed margin test for the programmed "1" cells. Therein, the
margin test has to be done several times with an increasing margin voltage (Recommendation: 25 mV step size).
By comparing the E²PROM readout of the previous mode step with the current step, which drives a flip from “1” to
“0”, defines the margin voltage (bit 4 of the register 08
where most of the "1" programmed cells are flipped should be directly in the middle between V
