For PIC18F8XXX devices, the Stack Pointer may
incorrectly increment during a table read operation
if the external memory bus wait states are enabled
(i.e.,
(CONFIG3L<7>
(MEMCON<5:4>) are not equal to ‘11’).
Work around
If using the external memory bus and performing
TBLRD operations with a non-zero wait state
(CONFIG3L<7>
(MEMCON<5:4>) are not equal to ‘11’), disable
interrupts by clearing the GIE/GIEH (INTCON<7>)
and PEIE/GIEL (INTCON<6>) bits prior to
executing any TBLRD operation.
Date Codes that pertain to this issue:
All engineering and production devices.
The A19:A16 address lines may release to their
inactive states at the same time as Read/Write bus
control pins (OE, WRH and WRL). This violates
bus timing condition described in Figure 26.5 and
Figure 26.6 of the data sheet. The result may be a
device on the memory bus detecting an address
change when a Read or Write is initiated.
This situation may be more likely to affect faster
peripheral memory devices (e.g., Flash RAMs).
Longer propagation delays on the control signal
lines, which can be influenced by stray capaci-
tance and other factors, are more likely to
adversely affect the situation.
Work around
Two workarounds are presented here. Others may
be available.
1. Use a hardware latch, triggered by falling
2. Add a delay circuit on the A19:A16 address

If Brown-out Reset (BOR) is disabled, then the
Power-up Timer (PWRT) gets disabled irrespec-
tive of the state of the PWRTEN Configuration bit
(CONFIG2L<0>).
Work around
Do either of the following:
edges on the ALE signal, on the A19:A16
address lines. This will hold the address until
WRL or WRH can transition to an inactive
state.
