If firmware clears a PWM Fault while a Fault con-
dition is asserted, an interrupt will not be
generated for the current Fault.
Work around
Firmware must poll the OCFLT bit to determine if a
Fault condition still exists.
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 reg-
ister to set to ‘1’. For example, DDPCON = 0x100.
Affected Silicon Revisions
The RXDA bit does not correctly reflect the RX
FIFO status after an overrun event.
Work around
1. Clear the OERR bit. The FIFO pointer will be

read.

47. Module: DMA

49. Module: JTAG
50. Module: Oscillator
In Pattern Match mode, the DMA module may not
append all of the CRC results to the result buffer.
Work around
Use firmware to read the CRC result and append
it to the result buffer.
Affected Silicon Revisions
Clock source switching may cause a general
exception or a 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.
Affected Silicon Revisions
On 64-pin devices, an external pull-up resistor is
required on the TMS pin for proper JTAG.
Work around
Connect a 100k-200k pull-up to the TMS pin.
Affected Silicon Revisions
Changing the PB divisor on the fly may generate
exceptions.
Work around
Ensure 8 NOP instructions precede the write to the
PBDIV bits and 8 NOP instructions follow the write
to the PBDIV bits.
