38.5.8 Transmit Bandwidth Sharing

The bandwidth sharing feature works as follows:

After a successful transmission of a message, the module will remain Idle for n arbitration bit times before the module attempts to transmit the next message; it suspends the next transmission.
After the device has received a message, the module can transmit the next message as soon as the bus is Idle.

This allows other nodes on the bus to transmit their messages, even though they are of lower priority.

The number of arbitration bit times between transmissions can be configured using the TXBWS[3:0] bits (C1CON[31:28]).
