The Output Compare module may reinitialize or
clear a Fault on an aborted read of the OCxCON
register. An aborted read occurs when a read
instruction in the CPU pipeline has started
execution, but is aborted due to an interrupt.
Work around
Disable interrupts before reading the contents of
the OCxCON register, and then re-enable
interrupts after reading the register.
Affected Silicon Revisions
In Slave mode with TXISEL = 0, a TX buffer
underrun condition will not assert the TX interrupt
flag.
Work around
None.
Affected Silicon Revisions
The TOKBUSY bit does not correctly indicate sta-
tus when a transfer completes within the Start of
Frame threshold.
Work around
Use a firmware semaphore to track when a token
is written to U1TOK. Firmware then clears the
semaphore when the transfer is complete.
Affected Silicon Revisions
In Host mode, the interval between the first two
SOF packets may be less than what is specified by
the USB specification.
Work around
None.

22. Module: WDT
23. Module: Oscillator
24. Module: Oscillator
When code-protect is enabled, the WDT is not
held in reset during the POR RAM Clear Sequence
(RCS). If the WDT period does not exceed the
RCS period, the WDT will reset the part and the
RCS sequence will restart.
Work around
Use WDT periods equal to or longer than 128 ms.
Since the RCS and WDT run concurrently,
firmware will have a reduced period in which to
service the WDT for the first time.
Affected Silicon Revisions
Clock switching and Two-Speed Start-up may
cause a general exception when the reserved bit 8
of the DDPCON register is ‘0’.
Work around
Ensure that the reserved bit 8 of the DDPCON
register to set to ‘1’. For example,
Affected Silicon Revisions
Clock source switching may cause a general
exception or POR when switching from a slow
clock to a fast clock.
Work around
Clock source switches should be performed by
first switching to the FRC, and then switching to
the target clock source.
