After a clock failure event, any write to the
OSCCON register erroneously clears the fail-safe
condition and attempts to switch to a new clock
source that is specified by the NOSC bits in the
OSCCON register.
Work around
After a clock failure event, perform the following
steps:
1. Write ‘000’ to the NOSC bits in the OSCCON
2. Modify the OSCCON register with any value
Affected Silicon Revisions
In Pattern Match mode, the DMA will generate up
to three additional byte writes to the destination
address, after the Pattern Detection event has
occurred, when performing transfers with the
DCHxSSIZ set to greater than 1.
Work arounds
Work around 1:
The destination buffer needs to be large enough to
accommodate the extra bytes (up to 3 extra bytes).
Work around 2:
Set the destination size register to 1.
Work around 3:
Set the source size register to 1.

9. Module: Output Compare
10. Module: PMP
The Output Compare module in PWM mode
outputs a high of period register (PRx) length when
attempting to use PWM values of 0x00 followed by
0x01.
Work around
Do not use a PWM value of 0x01.
Affected Silicon Revisions
In PMP Slave 4B Buffer mode, if the underflow
Status bit OBF (PMSTAT<6>) is cleared at the
same time a PMP read is attempted, the PMP
could receive incorrect data.
Work around
The CPU can read the underflow flag OBUF and
set/clear an I/O pin for the external master device
to read. The state of the pin should indicate to the
external master device that an underflow has
occurred and no additional reads should occur
until the underflow status has been cleared by the
CPU.
