msCAN08 Controller (msCAN08)
Message storage
An overrun conditions occurs when both, the foreground and the
background receive message buffers are filled with correctly received
messages and a further message is being received from the bus. The
latter message will be discarded and an error interrupt with overrun
indication will occur if enabled. The over-writing of the background buffer
is independent of the identifier filter function. While in the overrun
situation, the msCAN08 will stay synchronized to the CAN bus and is
able to transmit messages but will discard all incoming messages.
