11. Module: I/O Port – Port Pin Multiplexed
with IC1
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.
12. Module: I
2
C
If there are two I
2
C devices on the bus, one of
them is acting as the Master receiver and the other
as the Slave transmitter. If both devices are config-
ured for 10-bit addressing mode, and have the
same value in the A10 and A9 bits of their
addresses, then when the Slave select address is
sent from the Master, both the Master and Slave
acknowledge it. When the Master sends out the
read operation, both the Master and the Slave
enter into Read mode and both of them transmit
the data. The resultant data will be the ANDing of
the two transmissions.
Work around
In all I
2
C devices, the addresses as well as bits
A10 and A9 should be different.
13. Module: Timer
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).
14. Module: PLL Lock Status Bit
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.
15. Module: PSV Operations
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
mode) with pre/post-decrement
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.
-merrata=psv_trap
Refer to the readme.txt file in the MPLAB C30
v3.11 tool suite for further details.
16. Module: I
2
C
In 10-bit Addressing mode, some address
matches don't set the RBF flag or load the receive
register I2CxRCV, if the lower address byte
matches the reserved addresses. In particular,
these include all addresses with the form
XX0000XXXX and XX1111XXXX, with the
following exceptions:
• 001111000X
• 011111001X
• 101111010X
• 111111011X
Work around
Ensure that the lower address byte in 10-bit
Addressing mode does not match any 7-bit
reserved addresses.
17. Module: I
2
C
When the I
2
C module is configured as a 10-bit
slave with and address of 0x102, the I2CxRCV
register content for the lower address byte is 0x01
rather than 0x02; however, the module
acknowledges both address bytes.
Work around
None.
