Bit 3 of CONFIG3H defaults to ‘0’ after a Bulk
Erase instead of ‘1’ as specified in the data sheet.
Work around
Program the HFOFST bit to the desired state after
a Bulk Erase. All MPLAB
currently perform this way.
Affected Silicon Revisions
In Asynchronous Receive mode, the RCIDL bit of
the BAUDCON register will properly go low when
an invalid Start bit less than 1/8th of a bit time is
received. The RCIDL bit will then stay low improp-
erly until a valid Start bit is received.
Work around
When monitoring the RCIDL bit, measure the
length of time between the RCIDL going low and
the RCIF flag going high. If this time is greater than
one character time, then restore the RCIDL bit by
resetting the EUSART module. The EUSART
module is reset when the SPEN bit of the RCSTA
register is cleared.
Affected Silicon Revisions
Setting a PORTB interrupt-on-change enable bit of
the IOCB register while the corresponding PORTB
input is high will cause an RBIF interrupt.
Work around
Set the IOCB bits to the desired configuration, then
read PORTB to clear the mismatch latches.
Finally, clear the RBIF bit before setting the RBIE
bit.

After extended stress, the Most Significant bit
(MSb) of the ADC conversion result can become
stuck at ‘0’. Conversions resulting in code 511 or
less are still accurate, but conversions that should
result in codes greater than 511 are, instead,
pinned at 511.
The potential for failures is a function of several
factors:
