Silicon Errata Issues
Note:
This document summarizes all silicon
errata issues from all revisions of silicon,
previous as well as current. Only the
issues indicated by the shaded column in
the following tables apply to the current
silicon revision (B8).
3. Module: Core
If a clock failure occurs when the device is in Idle
mode, the oscillator failure trap does not vector to
the Trap Service Routine. Instead, the device will
simply wake-up from Idle mode and continue code
execution if the Fail-Safe Clock Monitor (FSCM) is
enabled.
Work around
1. Module: JTAG
When the JTAG is disabled, the pull-up resistor on
the TDI pin (Pin 35/RA9) will stay enabled on the
44-pin variants of the device. This can cause the
device to draw extra current when asleep if the pin
is used as an input and held low.
Work around:
The pin will not draw extra current if any of the
following work around techniques are used:
• The pin is used as an output.
• The pin is driven high as an input.
• JTAG is enabled.

2. Module: Low-Voltage Detect (LVD)
The Low-Voltage Detect interrupt will not occur if
the device comes out of Reset in a low-voltage
state. To trigger an interrupt, the voltage must
decrease to a low-voltage range while the device
is running.
Work around
None.
Affected Silicon Revisions

Whenever the device wakes up from Idle (assuming
the FSCM is enabled), the user software should
check the status of the OSCFAIL bit (INTCON1<1>)
to determine whether a clock failure occurred, and
then perform an appropriate clock switch operation.

4. Module: Core
If a RAM read is performed on the instruction
immediately prior to enabling Doze mode, then an
extra read event will occur when Doze mode is
enabled. On most SFRs and on user RAM space,
this will have no visible effect. However, this can
cause registers which perform actions on reads,
such as auto-incrementing or decrementing a
pointer or removing data from a FIFO buffer, to
repeat that action, possibly resulting in lost data.
Work around
On the instruction prior to entering Doze mode, be
sure not to read a register which performs a secondary action. Examples of this would be UARTx
and SPIx FIFO buffers, and the RTCVAL registers.
The easiest way to ensure this does not occur is to
execute a NOP instruction before entering Doze
mode.

On a Brown-out Reset, both the BOR and POR
bits may be set. This may cause the Brown-out
Reset condition to be indistinguishable from the

The PIC24FJ16GA002 and PIC24FJ16GA004
devices have 8K of data RAM implemented
instead of 4K. This will cause the address error
trap not to function for addresses between 2000h
and 27FFh.
With the External Interrupt 0 (INT0) selected to start
an A/D conversion (SSRC<2:0> = 001), the device
may not wake-up from Sleep or Idle mode if more
than one conversion is selected per interrupt
(SMPI<3:0> <> 0000). Interrupts are generated
correctly if the device is not in Sleep or Idle mode.
Work around
Work around
Do not access RAM beyond address 17FFh to
maintain software compatibility with future device
revisions.
Configure the A/D to generate an interrupt after
every conversion (SMPI<3:0> = 0000). Use
another wake-up source, such as the WDT or
another interrupt source, to exit the Sleep or Idle
mode. Alternatively, perform A/D conversions in
Run mode.

The AD1PCFG and AD1CHS registers allow
unimplemented channels to be selected. If these
channels are selected, they will read as if tied to
VSS. These channels should be disabled.
Work around
Disable channels, AN13 and AN14, in the
AD1PCFG register by ensuring that bits 13 and 14
are cleared.
Ensure that bits 5 and 12 of AD1CHS are maintained cleared. If these bits are set, it will cause the
A/D to reference channels AN16-31.

10. Module: I2C™ (I2C1, SDA Line State)
11. Module: UART
When using I2C1, the SDA1 line state may not be
detected properly unless it is first held low for
150 ns after enabling the I2C module.
When the UARTx is in High-Speed mode, BRGH
(UxMODE<3>) is set; some optimal UxBRG
values can cause reception to fail.
In Master mode, this error may cause a bus collision to occur instead of a Start bit transmission.
Transmissions after the SDA1 pin that have been
held low will occur correctly.
Work around
In Slave mode, the device may not Acknowledge
the first packet sent after enabling the I2C module.
In this case, it will return a NACK instead of an
ACK. The device will correctly respond to packets
after detecting a low level on the line for 150 ns.
The I2C2 module operates as expected and does
not exhibit this issue.
Test UxBRG values in the application to find a
UxBRG value that works consistently for more highspeed applications. The user should verify that the
UxBRG baud rate error does not exceed the application limits. If possible, it is recommended to use a
comparable baud rate in Low-Speed mode.
Affected Silicon Revisions
A3/
A4

Work around
Using an external device or another I/O pin from
the microcontroller, drive the SDA1 pin low.
If no external devices or additional I/O pins are
available, it is sometimes possible to perform the
work around internally, using the following steps:
• With the module in Master mode, configure the
RB9 pin as an output.
• Clear the LATB9 bit (for the default I2C1
assignment) or LATB5 (for the alternate I2C1
assignment) to drive the pin low.
• Enable I2C1 by setting the I2CEN bit
(I2C1CON<15>).
Note that this action could appear to be a Start bit
to an I2C slave device on the bus if the RB8/SCL1
pin is not driven low prior to driving RB9/SDA1 low.
It may be necessary to add additional capacitance
to the SDA1 bus in order to maintain the low logic
level long enough for the module to detect the low
logic level. Make sure that when adding capacitance, that the application does not violate the I2C
timing specifications.
In Slave mode, the I2C master device on the bus
must either pull the SDAx line low, then high again,
prior to sending the first packet to the device, or
must resend the first packet.
Note that 150 ns is the absolute maximum time
required to avoid the issue. It is possible to work
around the issue using a shorter delay in some
devices.

12. Module: UART
When the UARTx is in High-Speed mode
(BRGH = 1), the auto-baud sequence can calculate
the baud rate as if it were in Low-Speed mode.
Work around
The calculated baud rate can be modified by the
following equation:
New BRG Value = (Auto-Baud BRG + 1) * 4 – 1
The user should verify that the baud rate error does
not exceed application limits.

When an auto-baud is detected, the receive interrupt may occur twice. The first interrupt occurs at
the beginning of the Start bit and the second after
reception of the Sync field character.
Work around
If a receive interrupt occurs, check the URXDA bit
(UxSTA<0>) to ensure that valid data is available.
On the first interrupt, no data will be present. The
second interrupt will have the Sync field character
(55h) in the receive FIFO.

14. Module: UART
17. Module: Output Compare
With the auto-baud feature selected, the Sync field
character (0x55) may be loaded into the FIFO as
data.
To prevent the Sync field character from being
loaded into the FIFO, load the UxBRG register with
either 0x0000 or 0xFFFF prior to enabling the
auto-baud feature (ABAUD = 1).
In PWM mode, the output compare module may
miss a compare event when the Current Duty
Cycle register (OCxRS) value is 0x0000 (0% duty
cycle) and the OCxRS register is updated with a
value of 0x0001. The compare event is only
missed the first time a value of 0x0001 is written to
OCxRS and the PWM output remains low for one
PWM period. Subsequent PWM high and low
times occur as expected.

The auto-baud may miscalculate for certain baud
rates and clock speed combinations, resulting in a
BRG value that is 1 greater or less than the
expected value. When UxBRG is less than 50, this
can result in transmission and reception failures
due to introducing error greater than 1%.
Work around
Test auto-baud calculations at various clock speed
and baud rate combinations that would be used in
applications. If an inaccurate UxBRG value is generated, manually correct the baud rate in user
code.

If the current OCxRS register value is 0x0000,

the desired value.

18. Module: SPI
When using Enhanced Buffer mode, some
indicator bits may be set at incorrect times:
• For slave transfers, the SRMPT bit
(SPIxSTAT<7>) is set early, after only 7 SCKx
periods.
• For Slave Interrupt modes (SISELx = 5), there
is a one SCKx period delay between the
interrupt event and the SPIxIF bit being set.
• There may be several instruction cycle delays
between the FIFO full or FIFO empty events
and the interrupt flags, or indicator bits being
set.
Work around
16. Module: UART
The UARTx module will not generate consecutive
Break characters. Trying to perform a back-toback Break character transmission will cause the
UARTx module to transmit the dummy character
used to generate the first Break character, instead
of transmitting the second Break character. Break
characters are generated correctly if they are
followed by non-Break character transmission.

In SPIx Slave mode (MSTEN = 0), with the slave
select option enabled (SSEN = 1), the peripheral
may accept transfers regardless of the SSx pin
state. The received data in SPIxBUF will be
accurate but not intended for the device.
Work around
There is a work around using the Peripheral Pin
Select (PPS) feature. One of the external interrupts (INT1 or INT2) can be mapped to the same
pin as the SSx signal or the SSx signal can be
mapped to a pin with interrupt-on-change (CNx)
functionality. If the SSx signal changes to low
(active), the interrupt flag will be set.
When an SPIx data received interrupt occurs, the
interrupt flag can be tested. If the interrupt mapped
to SSx did not occur, discard the data.

When using Enhanced Buffer mode, an interrupt
will not occur if the following conditions exist:
• SPIx Buffer Interrupt mode, SISEL<2:0>
(SPIxSTAT<4:2>), is set to interrupt when the
Shift register is empty (SISEL<2:0> = 101).
• Slave Select mode is enabled (SSEN = 1).
This only occurs when Enhanced mode, Slave
Select mode and interrupt on Shift register empty
are all enabled. In other modes, the interrupt will
work correctly.
Work around
When Slave Select mode is enabled, interrupting
on SPIxSR empty and TX empty will occur at the
same time. Therefore, interrupting on TX FIFO
empty (SISEL<2:0> = 110) can be used as an
alternative to interrupting when the Shift register is
empty (SISEL<2:0> = 101).

22. Module: I/O Ports
During Power-on Reset (POR), the device may
drive the OSCO/RA3 pin as a clock out output for
approximately 20 S. During this time, the pin will
be driven high and low rather than being set to
high-impedance. This may cause issues on
designs that use the pin as a general purpose I/O.
Designs should be reviewed to ensure that their
intended operation will not be disrupted if the pin is
driven during POR.

When entering the SHIFT_DR state while in

edge may be generated, causing JTAG and ICSP
communications to lose synchronization. This
prevents device programming using ICSP over

operates as expected.
The error causes data, from the instruction
following the ALCFGRPT instruction, to overwrite

When the I2C module is operating in Slave mode,
after the ACKSTAT bit is set when receiving a
NACK from the master, it may be cleared by the
reception of a Start or Stop bit.
Due to this issue, the state of ACKSTAT, after a
transmission finishes, will vary depending on the
device revision. On revisions with this issue,
ACKSTAT will be clear at the end of the transmission, and will remain clear until the next NACK is
received from the Master. On revisions without the
issue, ACKSTAT will be set at the end of a transmission and will remain set until receiving an ACK
from the Master.
Work around
Store the value of the ACKSTAT bit immediately
after receiving a NACK from the master.

26. Module: I2C
28. Module: I/O (Peripheral Pin Select)
Bit and byte-based operations may not have the
intended affect on the I2CxSTAT register. It is
possible for bit and byte operations, performed on
the lower byte of I2CxSTAT, to clear the BCL bit
(I2CxSTAT<10>). Bit and byte operation performed on the upper byte of I2CxSTAT, or on the
BCL bit directly, may not be able to clear the BCL
bit.
Work around
Modifications to the I2CxSTAT register should be
done using word writes only. This can be done in
‘C’ by always writing to the register itself and not
the individual bits. For example, the code,
I2C1STAT &= 0xFBFF, will force the compiler to
use a word-based operation to clear the BCL bit.
In assembly, it is done by not using BSET or BCLR
instructions, or instructions with the .b modifier.

The remappable pin functions multiplexed to some
pins do not have a higher priority than fixed digital
signals assigned to those pins. By design, a
remapped digital function should always have
priority over any other fixed digital function on the
same pin.
Using these remappable and specific fixed digital
functions at the same time may cause conflicts
and unexpected results on:
• RP12 and PMD0
• RP18 and PMA2 (40-pin and 44-pin
devices only)
No other fixed digital functions are affected.
Work around
On the affected pins, enable either the remappable
peripherals, or the specific fixed digital peripherals,
but not both at the same time.

27. Module: UART
When the UARTx is configured for IR interface
operations (UxMODE<9:8> = 11), the 16x baud
clock signal on the BCLK pin will only be present
when the module is transmitting. The pin will be
Idle at all other times.
The UARTx error interrupt may not occur, or occur
at an incorrect time, if multiple errors occur during
a short period of time.

Under certain circumstances, the PERR and
FERR error bits may not be correct for all bytes in
the receive FIFO. This has only been observed
when both of the following conditions are met:
If an instruction producing a read-after-write stall
condition is executed inside a REPEAT loop, the
instruction will be executed fewer times than was
intended. For example, this loop:
• the UARTx receive interrupt is set to occur when
the FIFO is full or 3/4 full (UxSTA<7:6> = 1x),
and
• more than 2 bytes with an error are received.
repeat #0xf
inc [w1],[++w1]
In these cases, only the first two bytes, with a
parity or framing error, will have the corresponding
bits indicate correctly. The error bits will not be set
after this.
will execute less than 16 times.
Work around
Avoid using REPEAT to repetitively execute
instructions that create a stall condition. Instead,
use a software loop using conditional branches.

33. Module: Memory (Program Space
Visibility)
When accessing data in the PSV area of data
RAM, it is possible to generate a false address
error trap condition by reading data located
precisely at the lower address boundary (8000h).
If data is read using an instruction with an autodecrement, the resulting RAM address will be
below the PSV boundary (i.e., at 7FFEh); this will
result in an address error trap.
This false address error can also occur if a 32-bit
MOV instruction is used to read the data at location,
8000h.
Work around
Do not use the first location of a PSV page
(address 8000h).
The MPLAB C Compiler (v3.11 or later) supports
the option, -merrata=psv_trap, to prevent it
from generating code that would cause this
erratum.

36. Module: I2C (Master Mode)
34. Module: RTCC
Under certain circumstances, the value of the Alarm
Repeat Counter (ALCFGRPT<7:0>) may be unexpectedly decremented. This happens only when a
byte write to the upper byte of ALCFGRPT is performed in the interval between a device POR/BOR
and the first edge from the RTCC clock source.
Under certain circumstances, a module operating
in Master mode may Acknowledge its own command addressed to a slave device. This happens
when the following occurs:
Do not perform byte writes on ALCFGRPT,
particularly the upper byte.
• 10-Bit Addressing mode is used (A10M = 1);
and
• the I2C master has the same two upper
address bits (I2CADD<9:8>) as the addressed
slave module.
Alternatively, wait until one period of the SOSC
has completed before performing byte writes to
ALCFGRPT.
In these cases, the master also Acknowledges the
address command and generates an erroneous I2C
slave interrupt, as well as the I2C master interrupt.

In Master mode, the SPIx Interrupt Flag (SPIxIF)
and the SPIRBF bit (SPIxSTAT<0>) may both
become set one-half clock cycle early, instead of
on the clock edge. This occurs only under the
following circumstances:
• Enhanced Buffer mode is disabled
(SPIBEN = 0); and
• the module is configured for serial data output
changes on transition from clock active to clock
Idle state (CKE = 1).
• Clear the A10M bit (I2CxCON<10> = 0) prior to
performing a Master mode transmit.

37. Module: I2C (Slave Mode)
Under certain circumstances, a module operating in
Slave mode may not respond correctly to some of
the special addresses reserved by the I2C protocol.
This happens when the following occurs:
• 10-Bit Addressing mode is used (A10M = 1);
and
• bits, A<7:1>, of the slave address
(I2CADD<7:1>) fall into the range of the
reserved 7-bit address ranges: ‘1111xxx’ or
‘0000xxx’.
In these cases, the Slave module Acknowledges
the command and triggers an I2C slave interrupt; it
does not copy the data into the I2CxRCV register
or set the RBF bit.

Do not set bits, A<7:1>, of the module’s slave

42. Module: Core (Code Protection)
When General Segment Code Protection has
been enabled (GCP Configuration bit is programmed), applications are unable to write to the
first 512 bytes of the program memory space
(0000h through 0200h). In applications that may
require the interrupt vectors to be changed during
run time, such as bootloaders, modifications to the
Interrupt Vector Tables (IVTs) will not be possible.
Work around
Create two new Interrupt Vector Tables, one each
for the IVT and AIVT, in an area of program space
beyond the affected region. Map the addresses in
the old vector tables to the new tables. These new
tables can then be modified as needed to the
actual addresses of the ISRs.
44. Module: UART (IrDA®)
When
IrDA
reception
is
enabled
(UxMODE<12> = 1), the operation of the RXINV
bit (UxMODE<4>) is the opposite of its description in the device data sheet (DS39881E); that is,
setting the bit configures the module for a logic
high Idle state, and clearing the bit configures the
module for a logic low Idle state. Using the bit as
described in the data sheet may result in
reception errors.
Work around
Invert the state of the RXINV bit. If the Idle state of
the received signal is logic high, set RXINV = 1. If
the Idle state of the received signal is logic low,
clear RXINV.

43. Module: SPI
SPIx operating in Enhanced Buffer mode
(SPIBEN = 1) may set the interrupt flag, SPIxIF,
before the last bit has been transmitted from the
Shift register. This issue only affects one of the
eight Interrupt modes, SISEL<2:0> = 101,
which generates an interrupt when the last bit
has shifted out of the Shift register, indicating the
transfer is complete. All other Interrupt modes in
Enhanced Buffer mode work as described in the
product data sheet.
Operations that immediately follow any manipulations of the DOZE<2:0> or DOZEN bits
(CLKDIV<14:11>) may not execute properly. In
particular, for instructions that operate on an
SFR, data may not be read properly. Also, bits
automatically cleared in hardware may not be

Multiple work arounds are available. Select
another Buffer Interrupt mode using the

Another option is to monitor the SRMPT bit
(SPIxSTAT<7>) to determine when the Shift
register is empty.

46. Module: SPI (Master Mode)
When operating in Enhanced Buffer Master mode,
the module may transmit two bytes or two words of
data with a value of 0h, immediately upon the
microcontroller waking up from Sleep mode. At the
same time, the module “receives” two words or two
bytes of data, also with the value of 0h.
The transmission of null data occurs even if the
Transmit Buffer registers are empty prior to the
microcontroller entering Sleep mode. The
received null data requires that the receive buffer
be read twice to clear the “received” data.
This behavior has not been observed when the
module is operating in any other mode.
48. Module: SPI (Framed SPIx Modes)
Framed SPIx modes, as described in the device
data sheet, are not supported. When using the

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
