Chapter 10 Freescale’s Scalable Controller Area Network (S12MSCANV2)
10.4.7.1
The MSCAN supports four interrupt vectors (see
(for details see sections from
(CANRIER),” to
10.4.7.2
At least one of the three transmit buffers is empty (not scheduled) and can be loaded to schedule a message
for transmission. The TXEx flag of the empty message buffer is set.
10.4.7.3
A message is successfully received and shifted into the foreground buffer (RxFG) of the receiver FIFO.
This interrupt is generated immediately after receiving the EOF symbol. The RXF flag is set. If there are
multiple messages in the receiver FIFO, the RXF flag is set as soon as the next message is shifted to the
foreground buffer.
10.4.7.4
A wake-up interrupt is generated if activity on the CAN bus occurs during MSCN internal sleep mode.
WUPE (see
10.4.7.5
An error interrupt is generated if an overrun of the receiver FIFO, error, warning, or bus-off condition
occurrs.

•
Overrun — An overrun condition of the receiver FIFO as described in
Structures,” occurred.
CAN Status Change — The actual value of the transmit and receive error counters control the
CAN bus state of the MSCAN. As soon as the error counters skip into a critical range (Tx/Rx-
warning, Tx/Rx-error, bus-off) the MSCAN flags an error condition. The status change, which
caused the error condition, is indicated by the TSTAT and RSTAT flags (see
