Silicon Errata Issues
1. Module: ECAN
© 2010 Microchip Technology Inc.
Note:
The WAKIF bit in the CxINTF register cannot be
cleared by software instruction after the device is
interrupted from Sleep due to activity on the CAN
bus.
When the device wakes up from Sleep due to CAN
bus activity, the ECAN module is placed in
operational mode. The ECAN Event interrupt
occurs due to the WAKIF flag. Trying to clear the
flag in the Interrupt Service Routine (ISR) may not
clear the flag. The WAKIF bit being set will not
cause
execution.
Work around
Although the WAKIF bit does not clear, the device
Sleep and ECAN Wake functions continue to work
as expected. If the ECAN event is enabled, the
CPU will enter the Interrupt Service Routine due to
the WAKIF flag getting set. The application can
maintain a secondary flag, which tracks the device
Sleep and Wake events.

Service
Routine
2. Module: ECAN
3. Module: UART
In
transmissions and receptions using ECAN with
DMA, intermittent DMA Write Collisions might get
generated, resulting in the generation of DMA
Error Traps. The ECAN messages would be
transmitted and received correctly even when
these DMA Error Traps occur.
Work around
Within the DMA Error Trap service routine in the
application software, read the DMACS0 register
and inspect the two XWCOLn (n = 0, 1, …,7) bits
corresponding to the DMA channels being used for
ECAN transmission and reception.
For example, if DMA Channel 1 is used for ECAN
Reception and DMA Channel 2 is used for ECAN
Transmission, inspect the XWCOL1 and XWCOL2
bits. If either of these bits is found to be set, clear
the DMACERR bit in the INTCON1 register and
return from the DMA Error Trap service routine.
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.
