Performing table read operations above the user
program
1FFFFFh) may yield erroneous results at the
extreme low end of the device’s rated temperature
range (-40°C).
This applies specifically to addresses above
1FFFFFh,
(200000h-200007h),
(300000h-30000Dh) and the device ID locations
(3FFFFEh and 3FFFFFh). User program memory
is unaffected.
Work around
Two possible work arounds are presented. Other
solutions may exist.
1. Do not perform table read operations on areas
2. Insert NOP instructions (specifically, literal
Date Codes that pertain to this issue:
All engineering and production devices.
In Extended Microcontroller mode, or Micro-
processor mode, the external memory interface is
inactive from 20000h to 2FFFFh. ALE and WRL
signals are inactive between 20000h and 2FFFFh.
Work around
Shift RAM space to 30000h and above, or as an
alternate solution, the PIC18F8720 device can be
used.
This issue will be resolved in a future version of
silicon.

The suggested optimal number is 4 instruc-
tions before and 8 instructions after each table
read. This may vary depending upon the
particular application and should be optimized
by the user.

4. Module: I/O Ports (Parallel Slave Port)
5. Module: A/D (External Voltage Reference)
While operating in Parallel Slave Port mode, the
OBF bit (PSPCON<6>) is supposed to be set
when a byte is written to either PORTD or LATD. It
has been noted that OBF may not be correctly set
when a byte is written to LATD. If the byte is written
to PORTD, then the OBF bit is set correctly.
Work around
To ensure the OBF bit is set correctly, write to
PORTD rather than LATD.
