7. Module: 32 kHz Low-Power (LP)
8. Module: DCI
© 2010 Microchip Technology Inc.
The LP oscillator is located on the SOSCO and
SOSCI device pins and serves as a secondary
crystal clock source for low-power operation. The
LP oscillator can also drive Timer1 for a real-time
clock application. The LP oscillator does not
function when the device is placed in Sleep mode.
Work around
If the application needs to wake-up periodically
from Sleep mode using an internal timer, the
Watchdog Timer may be enabled prior to entering
Sleep mode. When the Watchdog Timer expires,
code execution will resume from the instruction
immediately following the SLEEP instruction.
Affected Silicon Revisions
The DCI module is enabled by setting the DCIEN bit
(DCICON1<15>) and disabled by clearing the
DCIEN bit. Once enabled, if the DCI module is
subsequently disabled by the application, the
module does not release the ownership of the
COFS, CSCK, CSDI and CSDO pins to the
associated port functions (RB9, RB10, RB11 and
RB12).
Work around
After disabling the DCI module by clearing the
DCIEN bit, the application should further set the
DCI Module Disable bit, DCIMD (PMD1<8>). The
port functions associated with the DCI module
(RB9, RB10, RB11 and RB12) may now be used.

9. Module: Output Compare
10. Module: Output Compare
If the desire duty cycle is ‘0’ (OCxRS = 0), the
module will generate a high level glitch of 1 T
The second problem is that on the next cycle after
the glitch, the OC pin does not go high, or in other
words, it misses the next compare for any value
written on OCxRS.
Work around
There are two possible solutions to this problem:
1. Load a value greater than ‘0’ to the OCxRS
2. If the application requires 0% duty cycles, the
Affected Silicon Revisions
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 and
When these events occur, the Output Compare
module will drive the pin low for one instruction
cycle (T

None. However, the user may use a timer interrupt
and write to the associated PORT register to
control the pin manually.

case, no 0% duty cycle is achievable.
Output Compare module can be disabled
for 0% duty cycles, and re-enabled for
