A glitch will be produced on an output compare pin
under the following conditions:
• The user software initially drives the I/O pin
• The output compare module is configured
When these events occur, the output compare
module will drive the pin low for one instruction
cycle (T
Work around
None. However, the user may use a timer interrupt
and write to the associated PORT register to
control the pin manually.
Affected Silicon Revisions
The Index Pulse Reset mode of the Quadrature
Encoder Interface (QEI) does not work properly
when used along with count error detection. When
counting upwards, the POSCNT register will incre-
ment one extra count after the index pulse is
received. The extra count will generate a false
count error interrupt.
Work around
There are multiple ways to work around this issue,
depending on the specific requirements of the
application:
1. Ignore count error interrupts when the counting
2. The user may disable count error interrupts by
3. The user may disable the index pulse reset

(QEICON<2>). Writing QEICON = 0x0600 will
provide a QEI interrupt each time an index
pulse is received, but the POSCNT register will
not be modified. The POSCNT register value
can be read in the QEI interrupt handler and
used as an offset value to calculate the
absolute position of the encoder disc with
respect to the index pulse.

13. Module: ADC
14. Module: PLL
ADC event triggers from the INT0 pin will not
wake-up the device from Sleep mode if the SMPI
bits are non-zero. This means that if the ADC is
configured to generate an interrupt after a certain
number of INT0 triggered conversions, the ADC
conversions will not be triggered and the device
will remain in Sleep. The ADC will perform
conversions and wake-up the device only if it is
configured to generate an interrupt after each INT0
triggered conversion (SMPI<3:0> = 0000).
Work around
None. If ADC event trigger from the INT0 pin is
required, initialize SMPI<3:0> to ‘0000’ (interrupt
on every conversion).
Affected Silicon Revisions
If 8x PLL mode is used, the input frequency range
is 5 MHz-10 MHz instead of 4 MHz-10 MHz.
Work around
None. If 8x PLL is used, make sure the input
crystal or clock frequency is 5 MHz or greater.
