The PIC18FXX2 Rev. C0 parts you have received
conform functionally to the Device Data Sheet
(DS39564B), except for the anomalies described
below.
All the issues listed here will be addressed in future
revisions of the PIC18FXX2 silicon.

Performing table read operations above the user

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
Three possible work arounds are presented. Other
solutions may exist.
1. Do not perform table read operations on areas
2. Insert NOP instructions (specifically, literal

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.

2. Module: Data EEPROM
When reading the data EEPROM, the contents of
the EEDATA register may be corrupted if the RD
bit (EECON1<0>) is set immediately following a
write to the address byte (EEADR). The actual
contents of the data EEPROM remain unaffected.
Work around
Do not set EEADR immediately before the
execution of a read. Write to EEADR at least one
instruction cycle before setting the RD bit. The
instruction between the write to EEADR and the
read can be any valid instruction, including a NOP.
