Section 19 Controller Area Network (RCAN-TL1)
19.4.2
RCAN-TL1 is considered in configuration mode or after a H/W (Power On Reset)/S/W (MCR[0])
reset or when in Halt mode. In both conditions RCAN-TL1 cannot join the CAN Bus activity and
configuration changes have no impact on the traffic on the CAN Bus.
• After a Reset request
The following sequence must be implemented to configure the RCAN-TL1 after (S/W or H/W)
reset. After reset, all the registers are initialised, therefore, RCAN-TL1 needs to be configured
before joining the CAN bus activity. Please read the notes carefully.

SW reset could be performed at any time by setting MCR[0] = 1.
Mailboxes are comprised of RAMs, therefore, please initialise all the mailboxes enabled by MBC.
If there is no TXPR set, RCAN-TL1 will receive the next incoming message. If there is a TXPR(s)
Timer can be started at any time after the Timer Control regs and Tx-Trigger Time are set.
set, RCAN-TL1 will start transmission of the message and will be arbitrated by the CAN bus.
If it loses the arbitration, it will become a receiver.
