When in 16-bit mode, the upper 16 bits of the
32-bit ICxBUF register contain Timer3 values.
Work around
Mask the upper 16 bits of the read value.
Example: result = 0xFFFF & IC1BUF
Affected Silicon Revisions
When programming the PIC32 using the 2-wire
PGC and PGD pins, programming data appears
as an output on the JTAG TDO pin.
Work around
Do not connect the TDO pin to a device that would
be adversely affected by rapid pin toggling during
programming.
Affected Silicon Revisions
In BRGH = 1 mode, the received data is not
sampled in the middle of the bit. This reduces the
UART’s baud rate mismatch tolerance.
Work around
Use BRGH = 0 mode.

28. Module: Oscillator

30. Module: Oscillator
A clock signal is present on the CLKO pin,
regardless of the clock source and setting of the
CLOCKOUT Configuration bit, under any of the
following conditions.
1. During a Power-on Reset.
2. During device programming.
3. After a JTAG erase. A clock is present on the
Work around
Do not connect the CLKO pin to a device that
would be adversely affected by rapid pin toggling
or a frequency other than that defined by the
oscillator configuration. Do not use the CLKO pin
as an input if the device connected to the CLKO
pin would be adversely affected by the pin driving
a signal out.
Affected Silicon Revisions
Enabling the primary programming/debug port
(PGC1/PGD1) on 64-lead variants disables the
external and internal references for the ADC,
making the ADC unusable.
Work around
Use the secondary programming/debug port.
Affected Silicon Revisions
After a Fail-Safe Clock Monitor (FSCM) event, the
clock source will be FRC. Firmware clock switch
requests to switch from FRC mode after an FSCM
event may fail. If the clock switch does fail,
subsequent retries by firmware will also fail and
the clock source will be FRC.
Work around
None.
