20. Module: Motor Control PWM – PWM
21. Module: I/O Port – Port Pin Multiplexed
22. Module: Timer
DS80398A-page 12
If the PTDIR bit is set (when PTMR is counting
down), and the CPU execution is halted (after a
breakpoint is reached), PTMR will start counting
up as if PTDIR was zero.
Work around
None.
If the user application enables the auto-baud
feature in the UART module, the I/O pin
multiplexed with the IC1 (Input Capture) pin cannot
be used as a digital input.
Work around
None.
When the timer is being operated in Asynchronous
mode using the secondary oscillator (32.768 kHz)
and the device is put into Sleep mode, a clock
switch to any other oscillator mode before putting
the device to Sleep prevents the timer from waking
the device from Sleep.
Work around
Do not clock switch to any other oscillator mode if
the timer is being used in Asynchronous mode
using the secondary oscillator (32.768 kHz).

23. Module: PLL Lock Status Bit
24. Module: PSV Operations
The PLL LOCK Status bit (OSCCON<5>) can
occasionally get cleared and generate an
oscillator failure trap even when the PLL is still
locked and functioning correctly.
Work around
The user application must include an oscillator
failure trap service routine. In the trap service
routine, first inspect the status of the Clock Failure
Status bit (OSCCON<3>). If this bit is clear, return
from the trap service routine immediately and
continue program execution.
An address error trap occurs in certain addressing
modes when accessing the first four bytes of an
PSV page. This only occurs when using the
following addressing modes:
• MOV.D
• Register Indirect Addressing (word or byte
Work around
Do not perform PSV accesses to any of the first
four bytes using the above addressing modes. For
applications using the C language, MPLAB C30
version 3.11 or higher, provides the following
command-line switch that implements a work
around for the erratum.

v3.11 tool suite for further details.
