16. 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 com-
mand-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.
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.
18. Module: I
2
C
With the I
2
C module enabled, the PORT bits and
external interrupt input functions (if any)
associated with the SCL and SDA pins do not
reflect the actual digital logic levels on the pins.
Work around
If the SDA and/or SCL pins need to be polled,
these pins should be connected to other port pins
in order to be read correctly. This issue does not
affect the operation of the I
2
C module.

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.
