PIC12F635/PIC16F636/639
9.1
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
of the read or write operation. The inability to clear the
WR bit in software prevents the accidental, premature
termination of a write operation.

R/W-x
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 EEDAT and EEADR registers will need
to be re-initialized.
Interrupt flag, EEIF bit of 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.
Note:
The EECON1, EEDAT and EEADR
registers should not be modified during a
data EEPROM write (WR bit = 1).
