Data EEPROM read-out protection
The read-out protection is enabled through an option bit (see
When this option is selected, the programs and data stored in the EEPROM memory are
protected against Read-out (including a re-write protection). In Flash devices, when this
protection is removed by reprogramming the option byte, the entire Program memory and
EEPROM is first automatically erased.
Both Program Memory and data EEPROM are protected using the same option bit.

Bits 7:2 = Reserved, forced by hardware to 0
Bit 1 = E2LAT Latch access transfer bit: this bit is set by software.
Bit 0 = E2PGM Programming control and status bit
If the E2PGM bit is cleared during the programming cycle, the memory data is not
guaranteed.

It is cleared by hardware at the end of the programming cycle. It can only be cleared by
software if the E2PGM bit is cleared
This bit is set by software to begin the programming cycle. At the end of the
programming cycle, this bit is cleared by hardware.
