In 16-Bit Asynchronous Counter mode (with or
without use of the Timer1 oscillator), the TMR1H
and TMR3H buffers do not update when TMRxL is
read.
This issue only affects reading the TMRxH regis-
ters. The timers increment and set the interrupt
flags as expected. The timer registers can also be
written as expected.
Work around
1. Use 8-bit mode by clearing the RD16 bit
2. Use the internal clock synchronization option
Date Codes that pertain to this issue:
All engineering and production devices.
The device current consumption is not reduced
significantly when the device enters IDLE mode.
The device does stop execution and peripherals
continue to run as expected.
Work around
None
Date Codes that pertain to this issue:
All engineering and production devices.
The A<19:16> EMB address lines and Read/Write
control pins (OE, WRH and WRL) are released to
their respective inactive states at the same time
violating timing condition mentioned in Figure 26.5
and Figure 26.6 in the data sheet. This may result
in peripheral device on the bus detecting an
address change when Write/Read is initiated. The
bus capacitance and signal delay on the address
and control lines can affect the probability of
invalid detection.
Work around
Two workarounds are available
1. Use a latch based on the falling edge of ALE to
2. Or, add a delay circuit to extend the valid time
(T1CON<7>).
by clearing the T1SYNC bit (T1CON<2>).
hold the A<19:16> signals.
for A<19:16> signals to ensure the address is
valid until Read/Write signals go inactive.
18. Module: External Memory Bus
19. Module: Core (Program Memory Space)
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.
Writes to program memory address 300000h, that
are not blocked, can cause the program memory
at different locations to be corrupted.
Work around
Do not write to address 300000h. If you wish to
modify the contents of the Configuration registers,
then modify the Configuration Words located at the
end of the user memory (7FF4h for PIC18FX5J10
devices and 3FF4h for PIC18FX4J10 devices) and
issue a Reset command. This will reload the
Configuration registers with the new configuration
setting.
