FEAR registers are used for program, erase and auto-verify. In program and erase mode, it is page
address and ignored the same least significant bits as the number of bits of page address. In auto-
verify mode, address increases automatically by one.
FEARs are write-only register. Reading these registers returns 24-bit checksum result

Data register. In no program/erase/verify mode, READ/WRITE of FECR read or write data from
EEPROM or Flash to this register or from this register to Flash or EEPROM.
The sequence of writing data to this register is used for EEPROM program entry. The mode entrance
sequence is to write 0xA5 and 0x5A to it in order.
