PIC18F2221/2321/4221/4321 FAMILY
FIGURE 7-2:
7.2
Several control registers are used in conjunction with
the TBLRD and TBLWT instructions. These include the:
• EECON1 register
• EECON2 register
• TABLAT register
• TBLPTR registers
7.2.1
The EECON1 register (Register 7-1) is the control
register for memory accesses. The EECON2 register is
not a physical register; it is used exclusively in the
memory
EECON2 will read all ‘0’s.
The EEPGD control bit determines if the access will be
a program or data EEPROM memory access. When
clear, any subsequent operations will operate on the
data EEPROM memory. When set, any subsequent
operations will operate on the program memory.
The CFGS control bit determines if the access will be
to the Configuration/Calibration registers or to program
memory/data
subsequent operations will operate on Configuration
registers regardless of EEPGD (see Section 24.0
“Special Features of the CPU”). When clear, memory
selection access is determined by EEPGD.

Program Memory
The FREE bit, when set, will allow a program memory
erase operation. When FREE is set, the erase
operation is initiated on the next WR command. When
FREE is clear, only writes are enabled.
The WREN bit, when set, will allow a write operation.
On power-up, the WREN bit is clear. The WRERR bit is
set in 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
cannot be cleared, only set, in software; it is cleared in
hardware at the completion of the write operation.
Note:
Note:
During normal operation, the WRERR bit
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 (PIR2<4>) is set
when the write is complete. It must be
cleared in software.
