The ECAN module may not store received data in
the correct location. When this occurs, the receive
buffers will become corrupted. In addition, it is also
possible for the transmit buffers to become
corrupted. This issue is more likely to occur as the
CAN bus speed approaches 1 Mbps.
Work around
Do not use the DMA with ECAN in Peripheral
Indirect mode. Use the DMA in Register Indirect
mode, Continuous mode enabled and Ping Pong
mode disabled. The receive DMA channel count
should be set to 8 words. The transmit DMA
channel count should be set for the actual
message size (maximum of 7 words for Extended
CAN messages and 6 words for Standard CAN
Messages). To simplify application error handling
while using this mode, only one TX buffer should
be used. While message filtering is not affected,
messages will not be stored at distinct RX buffers.
Instead all messages are stored contiguously in
memory. The start of this memory is pointed to by
the receive DMA channel. The application must
still clear RXFUL flags and other interrupt flags.
The application must manage the RX buffer
memory.
Affected Silicon Revisions
The EXCH instruction does not execute correctly.
Work around
If
recommended work around is to replace:
EXCH Wsource, Wdestination
with:
PUSH Wdestination
MOV Wsource, Wdestination
POP Wsource
If using the MPLAB C30 C compiler, specify the
compiler option: -merrata=exch (Project > Build
Options > Projects > MPLAB C30 > Use Alternate
Settings).

19. Module: SPI
20. Module: UART
Writing to the SPIxBUF register as soon as the
TBF bit is cleared will cause the SPI module to
ignore the written data. Applications which use SPI
with DMA will not be affected by this erratum.
Work around
After the TBF bit is cleared, wait for a minimum
duration of one SPI Clock before writing to the
SPIxBuf register.
Alternatively, do one of the following:
1. Poll the RBF bit and wait for it to get set before
2. Poll the SPI Interrupt flag and wait for it to get
3. Use an SPI Interrupt Service Routine.
4. Use DMA.
Affected Silicon Revisions
The UART module will not generate consecutive
break characters. Trying to perform a back-to-back
Break character transmission will cause the UART
module to transmit the dummy character used to
generate the first Break character instead of
transmitting the second Break character. Break
characters are generated correctly if they are
followed by non-Break character transmission.
Work around
None.
