When reading EEPROM, the contents
of the EEDATA register may become cor-
rupted in the second instruction cycle
after setting the RD bit (EECON1<0>).
The result returned from an EEPROM
read operation can be corrupted if the
RD bit is set immediately following the
loading of the EEADR register.
Writes to EEPROM memory may not
succeed if the internal voltage reference
is not set.
Writes to program memory may not
succeed if the internal voltage reference
is not set.
A GOTO instruction placed at the reset
vector may not execute.
If a high-priority interrupt occurs during
a two-cycle instruction which modifies
WREG, BSR or STATUS, the fast-interrupt
return mechanism (via shadow regis-
ters) will restore the value held by the
register before the instruction.
Peripheral flags may be erroneously af-
fected if the BSR register holds the value
15, and an instruction is executed that
holds the value C9h in its 8 least signif-
icant bits.
If a peripheral interrupt occurs during a
TBLWT operation, data can be corrupted.
Self write operations initiated from and
acting upon a range within the same side
of the 4000h boundary may fail based
on sequences of instructions executed
following the write.
The
eeprom_read library function read
EEDATA immeadiately.
The compiler is not affected by this is-
sue.

No workaround applied
Additional NOP instruction inserted at
reset vector if following instruction is
GOTO.
Additional code reloads the shadow reg-
isters with the correct values of WREG,
STATUS and BSR.
A warning will be issued if the instruc-
tion MOVLB 15 instruction is detected in
the execuble code.
Library routine flash_write() will tem-
porarily disable all applicable interrupt-
enable bits before execution of a TBLWT
instruction.
