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
Register (base_address + 0x02). This command is taken into account if the channel
aborted is not transmitted. When this abort command is really done, the TSS463AA 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.
