52. 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.

53. Module: UART (UxE Interrupt)

The UART error interrupt may not occur, or may

occur at an incorrect time, if multiple errors occur

during a short period of time.

Work around

Read the error flags in the UxSTA register

whenever a byte is received to verify the error

status. In most cases, these bits will be correct,

even if the UART error interrupt fails to occur.

54. Module: UART (IrDA)

When the UART is operating in 8-bit mode

(PDSEL = 0x) and using the IrDA encoder/decoder

(IREN = 1), the module incorrectly transmits a data

payload of 80h as 00h.

Work around

None.
