TSS461F
Failure cases:- Code viol (CV error bit)
–
Acknowledge error (ACKE error bit)
–
CRC error (FCSE error bit)
It should be noticed that contention is considered as normal CSMA/CD protocol and,
therefore, is not taken into account in failure cases. So, an 'infinite' number of attempts can
be performed if bus contention occurs continuously.
There is only one retries counter for all channels. When the user writes the Max_Retries value,
all channels start their transmission with this parameter.
Rearbitrate
The purpose of rearbitrate feature is to postpone a channel already in transmission in order to
authorize an higher priority (see section “Priority Among the Different Channels”) message to be
transmit.
Typical Example
Max_retries = 1 (2 transmissions attempts).
If Ch 8 is in a the retry loop and the user wants to transmit the Ch 5 without waiting the end
of the loop, the user can use the rearbitrate command.
Then, the TSS461F will wait the end of the current transmission, reload the retries counter
and enable the Ch 5 to transmit.
At the end of this transmission Ch5, either when the attempt is successful or either when the
exceeded retry count is reached, the retries counter is reloaded and the transmission is
activated for the Ch 8 again.
