<Configuration> Cycle Time varies between L and Time_Ref + L

⎯ Change from Init_Watch_Trigger to Watch_Trigger

⎯ Message status count

Cycle Time = 0

RCAN-TL1 offers the two registers TCMR0 and TCMR2 as H/W support for

Init_Watch_Trigger and Watch_Trigger respectively. The SW is requested to enable

TCMR0 and disable TCMR2 up to the first reference message is detected on the CAN Bus

and then disable TCMR0 and enable TCMR2.- Schedule Synchronization state machine.

Only reception of Next_is_Gap interrupt is supported. The application needs to take care of

stopping all transmission at the end of the current basic cycle by setting the related TXCR

flags.Master-Slave Mode control.

Only automatic cycle time synchronization and CCR increment is supported.

Software has to count scheduling errors for periodic messages in exclusive windows.
