PIC18F47J13 FAMILY
FIGURE 7-2:
7.2
Several control registers are used in conjunction with
the TBLRD and TBLWT instructions. Those are:
• 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 WPROG bit, when set, will allow programming
two bytes per word on the execution of the WR
command. If this bit is cleared, the WR command will
result in programming on a block of 64 bytes.

The Table Pointer actually points to one of 64 holding registers, the address of which is determined by
TBLPTRL<5:0>. The process for physically writing data to the program memory array is discussed in

Program Memory
Holding Registers
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:
During normal operation, the WRERR is
read as ‘1’. This can indicate that a write
operation was prematurely terminated by
a Reset or a write operation was
attempted improperly.
