5.0
The data EEPROM is a nonvolatile memory array,
separate from the data RAM and program memory,
which is used for long-term storage of program data. It
is not directly mapped in either the register file or
program memory space but is indirectly addressed
through the Special Function Registers (SFRs). The
EEPROM is readable and writable during normal
operation over the entire V
Four SFRs are used to read and write to the data
EEPROM as well as the program memory. They are:
• EECON1
• EECON2
• EEDATA
• EEADR
The data EEPROM allows byte read and write. When
interfacing to the data memory block, EEDATA holds
the 8-bit data for read/write and the EEADR register
pair hold the address of the EEPROM location being
accessed.
The EEPROM data memory is rated for high erase/write
cycle endurance. A byte write automatically erases the
location and writes the new data (erase-before-write).
The write time is controlled by an on-chip timer; it will
vary with voltage and temperature as well as from chip-
to-chip. Please refer to parameter US122
in
limits.
5.1
The EEADR register is used to address the data
EEPROM for read and write operations. The 8-bit
range of the register can address a memory range of
256 bytes (00h to FFh).
5.2
Access to the data EEPROM is controlled by two
registers: EECON1 and EECON2. These are the same
registers which control access to the program memory
and are used in a similar manner for the data
EEPROM.

(Table 27-13
Preliminary
The EECON1 register
register for data and program memory access. Control
bit EEPGD determines if the access will be to program
or data EEPROM memory. When the EEPGD bit is
clear, operations will access the data EEPROM
memory. When the EEPGD bit is set, program memory
is accessed.
Control bit, CFGS, determines if the access will be to
the Configuration registers or to program memory/data
EEPROM memory. When the CFGS bit is set,
subsequent operations access Configuration registers.
When the CFGS bit is clear, the EEPGD bit selects
either program Flash or data EEPROM memory.
The WREN bit, when set, will allow a write operation.
On power-up, the WREN bit is clear.
The WRERR bit is set by hardware when the WR bit is
set and cleared when the internal programming timer
expires and the write operation is complete.
The WR control bit initiates write operations. The bit
can be set but not cleared by software. It is cleared only
by hardware at the completion of the write operation.
Control bits, RD and WR, start read and erase/write
operations, respectively. These bits are set by firmware
and cleared by hardware at the completion of the
operation.
The RD bit cannot be set when accessing program
memory (EEPGD = 1). Program memory is read using
table read instructions. See
and Table Writes”
The EECON2 register is not a physical register. It is
used exclusively in the memory write and erase
sequences. Reading EECON2 will read all ‘0’s.
Note:
Note:
PIC18F/LF1XK50
During normal operation, the WRERR
may read as ‘1’. This can indicate that a
write operation was prematurely termi-
nated by a Reset, or a write operation was
attempted improperly.
The EEIF interrupt flag bit of the PIR2
register is set when the write is complete.
It must be cleared by software.
