Under specific conditions, the TXBxSIDH register
of the pending message for transmission may be
corrupted. The following conditions must exist for
this event to occur:
1. A transmit message must be pending.
2. All of the receive buffers must be full and a

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 6 is an
example of how to disable a pending transmission.
