Figure 33. Disable Channel After Rearbitrate

In this case, the TSS463B completes the current attempt (Ch8) and lets the transmission go into the new channel (Ch5 if

validated), otherwise it stops all attempts on the current channel.

Abort

An abort command is dedicated to channels already enabled in transmission or in in-

frame response. For example, this command can be used to break the retry procedure

on one channel.

Abort channel is done by setting the Error bit (CHER) in the Message Length and Status

aborted is not transmitted. When this abort command is really done, the TSS463B set to

1 the Transmitted bit (CHTx) of the Message Length and Status Register.

The abort mechanism is integrated into the transmit function. This mainly means, abort,

priority and retries live together in the transmit function.
