The data EEPROM is readable and writable during
normal operation over the entire V
memory is not directly mapped in the register file
space. Instead, it is indirectly addressed through the
Special Function Registers (SFR).
There are four SFRs used to read and write the
program and data EEPROM memory. These registers
are:
• EECON1
• EECON2
• EEDATA
• EEADR
The EEPROM data memory allows byte read and write.
When interfacing to the data memory block, EEDATA
holds the 8-bit data for read/write and EEADR holds the
address of the EEPROM location being accessed. The
PIC18FXX8 devices have 256 bytes of data EEPROM
with an address range from 00h to FFh.
The EEPROM data memory is rated for high erase/
write cycles. A byte write automatically erases the loca-
tion and writes the new data (erase-before-write). The
write time is controlled by an on-chip timer. The write
time will vary with voltage and temperature, as well as
from chip-to-chip. Please refer to the specifications for
exact limits.

range. The data
5.1
The address register can address up to a maximum of
256 bytes of data EEPROM.
5.2
EECON1 is the control register for EEPROM memory
accesses.
EECON2 is not a physical register. Reading EECON2
will read all ‘0’s. The EECON2 register is used
exclusively in the EEPROM write sequence.
Control bits, RD and WR, initiate read and write opera-
tions, respectively. These bits cannot be cleared, only
set, in software. They are cleared in hardware at the
completion of the read or write operation. The inability
to clear the WR bit in software prevents the accidental
or 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 oper-
ation. In these situations, the user can check the
WRERR bit and rewrite the location. It is necessary to
reload the data and address registers (EEDATA and
EEADR) due to the Reset condition forcing the
contents of the registers to zero.
Note:
EECON1 and EECON2 Registers
EEADR Register
Interrupt flag bit, EEIF in the PIR2 register,
is set when write is complete. It must be
cleared in software.
