General Description
The AS8202 communications controller is an integrated device supporting serial
communication according to the TTP/C specification. It performs all communications tasks such
as reception and transmission of messages in a TTP
cluster without interaction of the host
CPU.
TTP
provides mechanisms that allow the deployment in high-dependability distributed real-
time systems. It provides following services:
predictable transmission of messages with minimal jitter
fault-tolerant distributed clock synchronisation
consistent membership service with small delay
masking of single faults
