In case of Merged Arbitrating Window the slot for transmission goes from the Tx_Trig of the

Mailbox opening the Window (TTW = 10 bin) to the end to the TEW of the Mailbox closing the

Window (TTW = 11 bin).The TXPR can be modified at any time. RCAN-TL1 ensures the

transmission of Time Triggered messages is always scheduled correctly. However, in order to

guarantee the correct schedule, there are some important rules that are :

• Example of Time Triggered System

The following diagram shows a simple example of how time trigger system works using RCAN-

TL1 in time slave mode.

⎯ TTT (Tx Trigger Time) can be modified during configuration mode.

⎯ TTT cannot be set outside the range of Time_Ref, which specifies the length of basic cycle.

⎯ TXPR is not automatically cleared for periodic transmission. If a periodic transmission

This could cause a scheduling problem.

needs to be cancelled, the corresponding TXCR bit needs to be set by the application.
