These bits allow the user to control the amount of retries the circuit will perform if any errors
occurred during transmission.
Table 5. Retries
Note:
•
•
These bits cannot be set by user; 001 must always be written to these bits.
The three different module types are supported (see section “VAN Frame”):
One: The TSS461E is an autonomous module (Rank 0), an synchronous access module (Rank
1) or a slave module (Rank 16).
Zero: The TSS461E is an synchronous access module (Rank 1) or a slave module (Rank 16).
000: TSS461A & B
001: TSS461C and TSS461E
Bus contention is not regarded as an error and that an infinite number of transmission attempts
will be performed if bus contention occurs continuously.
