Glossary
Buffer Control Unit. Handles message buffer access.
Communication Controller
Clock Domain Crosser
Controller Host Interface
The actual length of a cycle in PT for the ideal controller (+/- 0 ppm)
External Bus Interface
FlexRay Memory. Memory to store message buffer payload, header, and status, and to store
synchronization frame related tables.
Frame Start Sequence
Host Interface. Provides host access to FlexRay module.
The FlexRay CC host MCU
Look Up Table. Stores message buffer header index value.
Message Buffer
Message Buffer Index: the position of a header field entry within the header area. If the header area
is accessed as an array, this is the same as the array index of the entry.
Message Buffer Number: Position of message buffer configuration registers within the register map.
For example, Message Buffer Number 5 corresponds to the MBCCS5 register.
