Silicon Errata Issues
Note:
3. Module: JTAG (Device Programming)
The JTAGEN Configuration bit can be programmed to ‘0’ while using the JTAG interface for
device programming. This may cause a situation
where JTAG programming can lock itself out of
being able to program the device.
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 (A6).
Work around
None.
1. Module: Core (RAM Operation)
If a RAM read is performed on the instruction
immediately prior to enabling Doze mode, an extra
read event may occur when Doze mode is
enabled. This has no effect on most SFRs and on
user RAM space. However, this could cause registers which also perform some action on a read
(such as auto-incrementing a pointer or removing
data from a FIFO buffer) to repeat that action,
possibly resulting in lost data or unexpected
operation.
Work around
Avoid reading registers which perform a secondary action (e.g., UARTx and SPIx’s FIFO buffers,
and the RTCVAL registers) immediately prior to
entering Doze mode.
If this cannot be avoided, execute a NOP
instruction before entering Doze mode.

Module: UART
When the UARTx is operating using two Stop bits
(STSEL = 1), it may sample the first Stop bit
instead of the second one. If the device being
communicated with is one using one Stop bit in its
communications, this may lead to framing errors.
Work around
None.

2. Module: Core (BOR)
When the on-chip regulator is enabled (ENVREG
tied to VDD), a BOR event may spontaneously
occur under the following circumstances:
• VDD is less than 2.5V, and either:
• the internal band gap reference is being used as
a reference with the A/D Converter
(AD1PCFG2<1> or <0> = 1) or comparators
(CMxCON<1:0> = 11); or
• the CTMU or the USB module is enabled.
Work around
Limit the following activities to only those times
when the on-chip regulator is not in Tracking mode
(LVDIF (IFS4<8>) = 0):
• Enabling the USB or CTMU modules
• Selecting the internal band gap as a reference
for the A/D Converter or the comparators
5. Module: I/O (PORTB)
When RB5 is configured as an open-drain output,
it remains in a high-impedance state. The settings
of LATB5 and TRISB5 have no effect on the pin’s
state.
Work around
If open-drain operation is not required, configure
RB5 as a regular I/O (ODCB<5> = 0).
If open-drain operation is required, there are two
options:
• Select a different I/O pin for the open-drain
function
• Place an external transistor on the pin and
configure the pin as a regular I/O

6. Module: SPI (Master Mode)
8. Module: USB
In Master mode, both the SPIx Interrupt Flag
(SPIxIF) and the SPIRBF bit (SPIxSTAT<0>) may
become set one-half clock cycle early, instead of
on the clock edge. This occurs only under the
following circumstances:
While operating in Host mode and attached to a
low-speed device through a full-speed USB hub,
the PRE signal may not be generated correctly.
This will result in not being able to communicate
correctly with the low-speed device.
• Enhanced Buffer mode is disabled (SPIBEN = 0)
• The module is configured for serial data output
changes on transition from clock active to clock
Idle state (CKE = 1)
Work around
If the application is using the interrupt flag to determine when data to be transmitted is written to the
transmit buffer, the data currently in the buffer may
be overwritten.
Connect low-speed devices directly to the
application and not through a USB hub.

Work around
Before writing to the SPIx buffer, check the SCKx pin

doing this. In this example, pin, RD1, functions as
the SPIx clock, SCKx, which is configured as Idle
low.

9. Module: USB (VUSB Regulator)
The USB internal voltage regulator does not
regulate to 3.3V. The USB internal voltage regulator
is an optional feature and is not required for USB
operation or compliance.

Disable the USB voltage regulator (DISUVREG
Configuration bit set to ‘1’) and supply 3.0V to 3.6V
from an external source to the VUSB pin.

7. Module: CTMU
When the CTMU module is selected as the trigger
source (SYNCSEL<4:0> = 11000), the output
compare or input capture module triggers may not
work.
Work around
Manually trigger the output compare and/or input
capture modules after a CTMU event is received.
Be certain to compensate for any time latency
required by manually triggering the module.

11. Module: USB
12. Module: UART (UERIF Interrupt)
The Bus Activity Interrupt Flag, ACTVIF, is active
only while the device is in Sleep mode. It will not
become set when the microcontroller is in a Run
mode.
The UARTx error interrupt may not occur, or occur
at an incorrect time, if multiple errors occur during
a short period of time.
Work around
Read the error flags in the UxSTA register whenever a byte is received to verify the error status. In
most cases, these bits will be correct, even if the
UARTx error interrupt fails to occur. For possible
exceptions, refer to Errata # 13.
The type of work around depends on the type of
application that the microcontroller is being used
for.
For Self-Powered Peripherals: After receiving a
Suspend command from the PC, do NOT suspend
or disable the USB module. In addition, do not
switch to a clock configuration that is incompatible
with USB operation (refer to the device data sheet
for USB compatible clock settings).
For Bus Powered Peripherals: After receiving a
suspend command from the PC (IDLEIF Interrupt
Flag = 1):
• Suspend the USB module (U1PWRC<1> = 1)
• Globally enable USB interrupts (IEC5<6> = 1)
• Specifically enable the bus activity interrupt
(U1OTGIE<4> = 1)
• Place the microcontroller into Sleep mode as
soon as possible
For Embedded Host Devices:
• Issue a suspend command to the peripheral
device
• Suspend the USB module (U1PWRC<1> = 1)
• Globally enable USB interrupts (IEC5<6> = 1)
• Place the microcontroller into Sleep mode as
soon as possible
As an alternate procedure, do NOT suspend or
disable the USB module and do not switch to a
clock configuration that is incompatible with USB
operation.

13. Module: UART (FIFO Error Flags)
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:
• The UARTx receive interrupt is set to occur
when the FIFO is full or ¾ full
(UxSTA<7:6> = 1x)
• More than 2 bytes with an error are received
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.

17. Module:
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)
• 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.
Work around
I2C™
Module (Master Mode)
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 set bits, A<7:1>, of the module’s slave
address equal to ‘1111xxx’ or ‘0000xxx’.

• 10-Bit Addressing mode is used (A10M = 1)
• The I2C Master has the same two upper
address bits (I2CADD<9:8>) as the addressed
slave module
In these cases, the Master also Acknowledges the
address command and generates an erroneous I2C
slave interrupt, as well as the I2C master interrupt.
Work around
Several options are available:
• When using 10-Bit Addressing mode, make
certain that the master and slave devices do not
share the same 2 MSbs of their addresses.

PIC24FJ256GB110 FAMILY
19. 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
auto-decrement, 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 the 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.
21. Module: Core (Instruction Set)
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:
repeat #0xf
inc [w1],[++w1]
will execute less than 15 times.
Work around
Avoid using REPEAT to repetitively execute
instructions that create a stall condition. Instead,
use a software loop using conditional branches.
The MPLAB C Compiler will not generate REPEAT
loops that cause this erratum.

22. Module: RTCC
The ICSP/ICD port pair, PGEC3/PGED3

device.
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.

23. Module: SPI (Enhanced Buffer Modes)
If the SPIx event interrupt is configured to occur
when the enhanced FIFO buffer is full
(SISEL<2:0> = 111), the interrupt may actually
occur when the 7th byte is written to the buffer,
instead of the 8th byte. The other enhanced buffer
interrupts function as previously described.
Work around
Do not use the Full Buffer Interrupt mode. The
SPITBF bit (SPIxSTAT<1>) reliably indicates when
the enhanced FIFO buffer is full and can be polled
instead of using the Full Buffer Interrupt mode.

24. Module: A/D Converter
When using PGEC1 and PGED1 to debug an
application on any 64-pin devices in this family, all
voltage references will be disabled. This includes
VREF+, VREF-, AVDD and AVSS. Any A/D
conversion will always equal 0x3FF.
Note: This issue only applies to 64-pin devices
in this family (PIC24FJ256GB106,
PIC24FJ192GB106,
and
PIC24FJ64GB106).
Work around
Use PGEC2 and PGED2 to debug any A/D
functionality.
Work around
Set SISEL<2:0> (SPIxSTAT<4:2>) to ‘101’. This
configures the module to generate an SPIx event
interrupt whenever the last bit is shifted out of the
shift register. When the SPIxIF flag becomes set,
the shift register is empty.

26. 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 (IVT) 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.

25. Module: SPI (Enhanced Buffer Mode)
In Enhanced Master mode, the SRMPT bit
(SPIxSTAT<7>) may erroneously become set for
several clock cycles in the middle of a FIFO transfer,
indicating that the shift register is empty when it is
not. This happens when both SPIx clock prescalers
are set to values other than their maximum
(SPIxCON<4:2> ≠ 000 and SPIxCON<1:0> ≠ 00).
27. Module: CTMU (A/D Trigger)
The CTMU may not trigger an automatic A/D conversion after the current source is turned off. This
happens even when the A/D trigger control bit,
CTTRIG (CTMUCON<8>), has been set.
Work around
Perform a manual A/D conversion by clearing the
SAMP bit (AD1CON1<1>) immediately after the
CTMU current source has been stopped.

The LPRC may not automatically restart following
BOR events (i.e., when supply voltage sags to

returns to above the BOR level). When this
happens, systems that use the LPRC clock may
not work. This includes the PLL, Two-Speed
Start-up, Fail-Safe Clock Monitor and the WDT.
Work around
For PLL issues: select a non-PLL Clock mode as
the initial start-up mode, using the FNOSC Configuration bits (CW2<10:8>). After the application has
initialized, switch to a PLL Clock mode in software
using the NOSC bits (OSCCON<10:8>). Allow
10 s to elapse between application start-up and a
software clock switch.
For WDT issues: disable the WDT by programming the FWDTEN bit (CW1<7>). After the
application has initialized, enable the WDT in software by setting the SWDTEN bit (RCON<5>).
Allow 10 s to elapse between application start-up

0001h. The compare event is only missed the first
time a value of 0001h is written to OCxRS and the
PWM output remains low for one PWM period.
Subsequent PWM high and low times occur as
expected.
Work around
If the current OCxRS register value is 0000h, avoid
writing a value of 0001h to OCxRS. Instead, write
a value of 0002h. In this case, however, the duty
cycle will be slightly different from the desired
value.

31. Module: Interrupts (INTx)
Writing to the INTCON2 register may cause an
external interrupt event (inputs on INT0 through
INT4) to be missed. This only happens when the
interrupt event and the write event occur during the
same clock cycle.
Work around
If this cannot be avoided, write the data intended
for INTCON2 to any other register in the interrupt
block of the SFR (addresses, 0080h to 00E0h);
then write the data to INTCON2.
Be certain to write the data to a register not being
actively used by the application, or to any of the
interrupt flag registers, in order to avoid spurious
interrupts. For example, if the interrupts controlled
by IEC5 are not being used in the application, the
code sequence would be:
IEC5 = 0x1E;
INTCON2 = 0x1E;
IEC5 = 0;
It is the user’s responsibility to determine an
appropriate register for the particular application.

32. Module: A/D Converter
Once
the
A/D
module
is
enabled
(AD1CON1<15> = 1), it may continue to draw
extra current, even if the module is later disabled
(AD1CON1<15> = 0).
Work around
In addition to disabling the module through the
ADON bit, set the corresponding PMD bit
(ADC1MD, PMD1<0>) to power it down
completely.
Disabling the A/D module through the PMD register also disables the AD1PCFG registers, which in
turn affects the state of any port pins with analog
inputs. Users should consider the effect on I/O
ports and other digital peripherals on those ports
when ADC1MD is used for power conservation.

34. Module: Output Compare (Interrupt)
Under certain circumstances, an Output Compare match may cause the interrupt flag (OCxIF)
to become set prior to the Change-of-State
(COS) of the OCx pin. This has been observed
when all of the following are true:
•
the module is in One-Shot mode
(OCM<2:0> = 001, 010 or 100);
one of the timer modules is being used as
the time base; and
a timer prescaler other than 1:1 is selected.
•
•
If the module is re-initialized by clearing
OCM<2:0> after the One-Shot compare, the
OCx pin may not be driven as expected.
Work around
After OCxIF is set, allow an interval (in CPU
cycles) of at least twice the prescaler factor to
elapse before clearing OCM<2:0>. For example,
for a prescaler value of 1:8, allow 16 CPU cycles
to elapse after the interrupt.
Affected Silicon Revisions
33. Module: Oscillator
The POSCEN bit (OSCCON<2>) has no effect
when a Primary Oscillator with PLL mode is
selected (COSC<2:0> = 011). If XTPLL, HSPLL
or ECPLL Oscillator mode are selected, and the
device enters Sleep mode, the Primary Oscillator will be disabled, regardless of the state of the
POSCEN bit.
XT, HS and EC Oscillator modes (without the
PLL) will continue to operate as expected.
Work around
None.

35. Module: CTMU
Using the CTMUMD bit (PMD4<2>) to selectively power down the module may reduce the
accuracy of the internal band gap reference
(VBG). In those cases where VBG is used as a
reference for other analog modules, the accuracy of measurements or comparisons may be
affected.
Work around
If the A/D Converter or Comparators are being
used with VBG selected as a reference, do not set
the CTMUMD bit.

37. Module: USB (Device Mode)
When using UTXISEL<1:0> = 01 (interrupt when
last character is shifted out of the Transmit Shift
Register), and the final character is being shifted
out through the Transmit Shift Register, the TX
interrupt may occur before the final bit is shifted
out.
Work around
If it is critical that the interrupt processing occurs
only when all transmit operations are complete,
after which, the following work around can be
implemented:
Hold off the interrupt routine processing by adding
a loop at the beginning of the routine that polls the
Transmit Shift Register empty bit, as shown in
Example 2.

In previous literature for this module, the
EPSTALL bits (U1EPn<1>) are described as
being only stall status indicator bits in Device
mode. In actual implementation, the EPSTALL
bits function as both status and control bits.
If the EPSTALL bit for endpoint ‘n’ is set (either
by the SIE hardware or manually in firmware),
both the IN and OUT endpoints, associated with
the endpoint, will send STALL packets when the
endpoint’s UOWN bit (BDnSTAT<15>) is also
set.
Work around
For Host Applications: No work around is
needed as hosts do not send STALL packets.
For Device Mode Applications: When it is necessary to stop sending STALL packets on an
endpoint, clear the endpoint’s respective
BSTALL (BDnSTAT<10>) and EPSTALL bits. If
the application firmware was developed based
on one of the examples in the Microchip USB
framework, this is already the default behavior of
the USB stack firmware (except Version 2.8); no
further work around is normally needed.
If a Device mode application was based upon
Version 2.8 of the USB framework, and the
application uses STALL packets on any of the
application endpoints (1-15), it is suggested to
update the application to the latest version.

38. Module: USB (Device and Host Modes)
In previous literature for this module, the
ACTVIF interrupt flag (U1OTGIR<4>) is
described as being asserted, based on state
changes detected on D+, D- or VBUS, when the
microcontroller is in Sleep mode. In actual
implementation, state changes on the
RF3/USBID pin also cause the ACTVIF flag to
be asserted.
As a result, logic input level changes on
RF3/USBID may cause ACTVIF to be
asserted, even in non-OTG applications that do
not use the USBID function. This may cause the
microcontroller to wake up unexpectedly.
Work around
For On-The-Go (OTG) Based Applications: No
work around is needed.
For non-OTG Device, Host or Dual-Role
Applications: If ACTVIF is used as a wake-up
source, it is recommended that the application be
designed so that RF3/USBID does not see any
changes while the microcontroller is in a
power-saving mode.
If RF3/USBID is not needed in the application, it
is recommended to configure it as a digital output.
If the RF3/USBID pin is configured as a digital
input, ensure that the signal provider does not
change the pin state while ACTVIF is enabled as
a wake-up source. If the pin is used as a general
purpose input, which can change while in the
USB Suspend state, check the IDIF flag
(U1OTGIR<7>) after waking up from an ACTVIF
event to determine if the wake-up event was
caused by a state change on RF3/USBID.

Voltage Regulator Pins Voltage
Regulator Pins
(ENVREG/DISVREG and
VCAP/VDDCORE)
Note:
When the regulator is enabled, a low-ESR (< 5Ω)
capacitor is required on the VCAP/VDDCORE pin to
stabilize the voltage regulator output voltage. The
VCAP/VDDCORE pin must not be connected to VDD and
must use a capacitor of 10 µF connected to ground. The
type can be ceramic or tantalum. Suitable examples of
capacitors are shown in Table 2-1. Capacitors with
equivalent specifications can be used.
The placement of this capacitor should be close to
VCAP/VDDCORE. It is recommended that the trace
length not exceed 0.25 inch (6 mm). Refer to
Section 29.0 “Electrical Characteristics” for
additional information.
When the regulator is disabled, the VCAP/VDDCORE pin
must be tied to a voltage supply at the VDDCORE level.
Refer to Section 29.0 “Electrical Characteristics” for
information on VDD and VDDCORE.

CONSIDERATIONS FOR CERAMIC
CAPACITORS
In recent years, large value, low-voltage, surface
mount ceramic capacitors have become very cost
effective in sizes up to a few tens of microfarad. The
low-ESR, small physical size and other properties
make ceramic capacitors very attractive in many types
of applications.
Ceramic capacitors are suitable for use with the internal voltage regulator of this microcontroller. However,
some care is needed in selecting the capacitor to
ensure that it maintains sufficient capacitance over the
intended operating range of the application.
Typical low-cost 10 µF ceramic capacitors are available
in X5R, X7R and Y5V dielectric ratings (other types are
also available, but are less common). The initial tolerance specifications for these types of capacitors are
often specified as ±10% to ±20% (X5R and X7R), or
-20%/+80% (Y5V). However, the effective capacitance
that these capacitors provide in an application circuit
will also vary based on additional factors, such as the
applied DC bias voltage and the temperature. The total
in-circuit tolerance is, therefore, much wider than the
initial tolerance specification.
The X5R and X7R capacitors typically exhibit satisfactory temperature stability (ex: ±15% over a wide
temperature range, but consult the manufacturer’s data
sheets for exact specifications). However, Y5V capacitors typically have extreme temperature tolerance
specifications of +22%/-82%. Due to the extreme
temperature tolerance, a 10 µF nominal rated Y5V type
capacitor may not deliver enough total capacitance to
meet minimum internal voltage regulator stability and
transient response requirements. Therefore, Y5V
capacitors are not recommended for use with the internal voltage regulator if the application must operate
over a wide temperature range.
 2008-2013 Microchip Technology Inc.
In addition to temperature tolerance, the effective
capacitance of large value ceramic capacitors can vary
substantially, based on the amount of DC voltage
applied to the capacitor. This effect can be very significant, but is often overlooked or is not always
documented.
A typical DC bias voltage vs. capacitance graph for
16V, 10V and 6.3V rated capacitors is shown in
Figure 2-4.

DC Bias Voltage (VDC)
When selecting a ceramic capacitor to be used with the
internal voltage regulator, it is suggested to select a
high-voltage rating, so that the operating voltage is a
small percentage of the maximum rated capacitor voltage. For example, choose a ceramic capacitor rated at
16V for the 2.5V core voltage. Suggested capacitors
are shown in Table 2-1.

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.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

applications and the like is provided only for your convenience
