The PIC18FXX39 Rev. B5 parts you have received

conform functionally to the Device Data Sheet

(DS30485A), except for the anomalies described

below.

All the problems listed here will be addressed in future

revisions of the PIC18FXX39 silicon.

1. Module: Program Memory

 2002 Microchip Technology Inc.

Data corruption may occur during a Table Write

operation if a peripheral interrupt also occurs. This

happens only when the interrupt enable bit (PIE or

INTCON register) for the corresponding interrupt

has also been set.

Work around

Before executing any Table Write instructions, dis-

able ALL peripheral interrupts. This is best done by

clearing all Interrupt Enable bits in the three Inter-

rupt Control registers (INTCON, INTCON2 and

INTCON3) and both Peripheral Interrupt Enable

registers (PIE1 and PIE2). After the Table Write is

complete, restore all INTCON and PIE registers to

their pre-instruction state.

Date Codes that pertain to this issue:

All engineering and production devices.

2. Module: Data EEPROM

EXAMPLE 1:

PIC18FXX39

When reading the data EEPROM, the contents of

the EEDATA register may become corrupted in the

second instruction cycle after the RD bit

(EECON1<0>) is set. The actual contents of the

EEPROM remains unaffected.

Work around

To ensure the integrity of the contents of EEDATA,

the register must be read in the instruction imme-

diately following the setting of the RD bit. Use the

movf or movff instructions to do this (see

Example 1).

Additionally, all interrupts must be disabled prior to

the read instruction sequence. Interruptions of the

sequence may have the same result of altering the

contents of EEDATA.

Date Codes that pertain to this issue:

All engineering and production devices.
