Under specific conditions, the TXBnSIDH register
of the pending message for transmission may be
corrupted. This occurs when the following
conditions exist:
• A transmit message is pending.
• All of the receive buffers are full and a received
• A receive buffer is made available (RXFUL
If (RXBnOVFL == 1)
message is in the Message Assembly Buffer
(MAB).
(RXBxCON<7>) set to ‘0’) at either of the
following times:
- When a Start-of-Frame (SOF) is recognized
- On the instruction cycle prior to the SOF
The timing of this event is crucial.

// Has an overflow occurred?
// Is a transmission pending?
// Clear transmit request
// Store transmission aborted status value
// Read receive buffer
// Was previous transmission aborted?
// Set transmit request
// Reset stored transmission aborted status
Work around
Ensure that a receive buffer overflow condition
does not occur and/or ensure that a transmit
request is not pending if a receive buffer
overflow condition does exist.
The pseudo code segment in Example 4 is an
example of how to disable a pending transmission.
This code is for illustration purposes only.
