17.4 Message Storage
17.4.1 Background
MC68HC912D60A — Rev. 3.1
Freescale Semiconductor
msCAN12 facilitates a sophisticated message storage system which
addresses the requirements of a broad range of network applications.
Modern application layer software is built upon two fundamental
assumptions:
1. Any CAN node is able to send out a stream of scheduled
2. The internal message queue within any CAN node is organized
messages without releasing the bus between two messages.
Such nodes will arbitrate for the bus right after sending the
previous message and will only release the bus when arbitration
is lost.
such that if more than one message is ready to be sent, the
highest priority message will be sent out first.
