The USB clock does not automatically suspend
when entering Sleep mode.
Work around
Turn off the USB clock before entering Sleep
mode.
Affected Silicon Revisions
The TRMT bit is asserted during the STOP bit
generation not after the STOP bit has been sent.
Work around
If firmware needs to be aware when the transmis-
sion is complete, firmware should add a half bit
time delay after the TRMT bit is asserted.
Affected Silicon Revisions
The fault override of the PWM output pin(s) does
not occur asynchronously; it is synchronized to the
PB clock. The synchronization takes up to 2 PB
clock periods for the fault event to tri-state the
PWM output pin.
Work around
None.
Affected Silicon Revisions
The SPIBUSY and SRMT bits assert 1 bit time
before the end of the transaction.
Work around
Firmware must provide a 1 bit time delay between
the assertion of these bits and performing any
operation that requires the transaction to be
complete.

41. Module: Output Compare
42. Module: USB
43. Module: USB
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
The TOKBUSY bit does not correctly indicate
status 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
The interval between the first two SOF packets
generated does not meet the USB specification.
The first count could be short due to an
uninitialized counter.
Work around
There is no work around for the non-compliant tim-
ing. It is recommended that firmware not send data
in the first frame.
