In 10-bit Addressing mode, some address

particular, these include all addresses with the
form “XX0000XXXX” and “XX1111XXXX”, with the
following exceptions:
• 001111000X
• 011111001X
• 101111010X
• 111111011X
Work around
The lower address byte in 10-bit Addressing mode
should not be a reserved address.
If the I

content for the lower address byte is 0x01 rather

Work around
None.
Under certain circumstances, the PERR and
FERR error bits may not be correct for all bytes in
the receive FIFO. This has only been observed
when both of the following conditions are met:
• The UART receive interrupt is set to occur
• More than two bytes with an error are received.
In these two circumstances, only the first two bytes
with a parity or framing error will have the
corresponding bits indicated correctly. The error
bits will not be set after this occurs.
Work around

dsPIC30F1010/202X
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:
