After Prog_Busy reads 0, the EEPROM is programmed. Verify
this programming by powering down the
clicking Read Addr:00. Expect to receive all 0s back, because
the ADuM4138 is unpowered. This read is so that the next read
is easier to see. The other read buttons can also be clicked, but it
is not necessary. Figure 15 shows all read buttons clicked while
the ADuM4138 is off.

Now power up the ADuM4138, and click all the read buttons.
It can then be seen that Bit 0 of GAIN_1 survives a power-up,
indicating that the EEPROM is programmed. The same steps
can be performed with the GAIN_1 field set to 0 to return the
EEPROM to its original programmed state, if desired (see
Figure 16).
