8.1
The EEADR register can address up to a maximum of
128 bytes of data EEPROM. Only seven of the eight
bits in the register (EEADR<6:0>) are required. The
MSb (bit 7) is ignored.
The upper bit should always be ‘0’ to remain upward
compatible with devices that have more data EEPROM
memory.
8.2
EECON1 is the control register with four low-order bits
physically implemented. The upper four bits are non-
implemented and read as ‘0’s.
Control bits RD and WR initiate read and write,
respectively. These bits cannot be cleared, only set, in
software. They are cleared in hardware at completion

WRERR
R/W-x
of the read or write operation. The inability to clear the
WR bit in software prevents the accidental, premature
termination of a write operation.
The WREN bit, when set, will allow a write operation.
On power-up, the WREN bit is clear. The WRERR bit is
set when a write operation is interrupted by a MCLR
Reset, or a WDT Time-out Reset during normal
operation. In these situations, following Reset, the user
can check the WRERR bit, clear it, and rewrite the
location. The data and address will be cleared,
therefore, the EEDATA and EEADR registers will need
to be re-initialized.
Interrupt flag bit EEIF in the PIR1 register is set when
write is complete. This bit must be cleared in software.
EECON2 is not a physical register. Reading EECON2
will read all ‘0’s. The EECON2 register is used
exclusively in the data EEPROM write sequence.
