Section 19 Controller Area Network (RCAN-TL1)

19.9.1
The RCAN-TL1 in this LSI has two channels and some of these channels can be used as a single
channel. When using multiple channels as a single channel, keep the following in mind.
1. No ACK error is detected even when any other nodes are not connected to the CAN bus. This
2. Internal arbitration for channels 0 and 1 is independently controlled to determine the order of
3. Do not set the same transmission message ID in both channels 0 and 1.

occurs when channel 1 transmits an ACK in the ACK field in response to a message channel 0
has transmitted.
Channel 1 receives a message which channel 0 has transmitted on the CAN bus and then
transmits an ACK in the ACK field. After that, channel 0 receives the ACK.
To avoid this, make channel 1 which is not currently used for transmission the listen-only
mode (TST[2:0] = B'001) or the reset state (MCR0 = 1). With this setting, only a channel
which transmits a message transmits an ACK.
transmission.
Although the internal arbitration is performed on 31 Mailboxes at a time, it is not performed on
64 Mailboxes at a time even though multiple channels function as a single channel.
Two messages may be transmitted from the two channels after arbitration on the CAN bus.
