falling edge of E2LAT bit.
It is not possible to read the latched data.
Special management of wrong EEPROM access:
If a read happens while E2LAT=1, then the data bus will not be driven.
If a write access happens while E2LAT=0, then the data on the bus will not be latched.
The data latches are cleared when the user sets E2LAT bit.
Care should be taken in the write routine: the software has to read back the data and rewrite
in case of failure.
