3.3.3.1
This flag indicates transmission conflicts, i.e. indicates that a reception is in progress when the controller
starts transmission. This bit indicates conflicts during transmission in static and dynamic segments.
0 – No transmission conflict detected.
1 – Transmission conflict detected.

The CC indicates status information for transmit message buffers only,
in the TXCON bit; the remaining bits are used to indicated receive status
information. Therefore, if a message buffer is configured as a receive or
receive FIFO message buffer, its TXCON bit is not used by the CC. If a
message buffer is configured as a transmit message buffer, only its
TXCON bit is updated by the CC, while the remaining bits are not used
by the controller.
Refer to
protocol states.
After reception of a null frame or an invalid frame, the controller updates
only the slot status vector of a selected receive message buffer or FIFO
buffer. Other fields (see
unaltered.
After reception of a valid frame, the controller updates the slot status
vector and the remainder of the receive message buffer or FIFO buffer.
After transmission of a frame, the controller updates the slot status
vector in the current transmit message buffer.
The controller updates a message buffer assigned to slot n within the first
macrotick of the slot n+1.
Empty static slots exhibit slot status 0x0000 on channel A and 0x0100
on channel B.
