In this example, a write operation is issued to write the data < 12 34 56 78 > to EEPROM
memory addressses 0000 to 003F by I2C communication.
Note that in the I2C answer, you are notified of whether the write cycle succeeded or failed
(see
Figure 72. Write cycle successful
Figure 73. Write cycle failed (no write cycle detected)
