Section 19 Controller Area Network (RCAN-ET)
19.6 Application Note
19.6.1 Configuration of RCAN-ET
RCAN-ET 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-ET cannot join the CAN Bus activity and
configuration changes have no impact on the traffic on the CAN Bus.
(1) After a reset request
The following sequence must be implemented to configure the RCAN-ET after (S/W or H/W)
reset. After reset, all the registers are initialized, therefore, RCAN-ET needs to be configured
before joining the CAN bus activity. Please read the notes carefully.
