• Message Transmission Request for Time Triggered communication
When the Time Triggered mode is used communications must fulfils the ISO11898-4
requirements.
The following procedure should be used.
⎯ Send RCAN-TL1 to reset or halt mode
⎯ Set TCMR0 to the Init_Watch_Trigger (0xFFFF)
⎯ Enable TCMR0 compare match setting bit 10 of TTCR0
⎯ Set TCMR2 to the specified Watch_Trigger value
⎯ Keep TCMR2 compare match disabled by keeping cleared the bit 12 of TTCR0
⎯ Set CMAX to the requested value (different from 111 bin)
⎯ Set TEW to the requested value
⎯ Configure the necessary Mailboxes for Time Trigger transmission and reception
⎯ Set LAFM for the 3 LSBs of Mailbox 31
⎯ Configure MCR, BCR1 and BCR0 to the requested values
⎯ If working as a potential time master:
⎯ Enable the TCNTR timer through the bit 15 of TTCR0
⎯ Move to Transmission_Reception mode
⎯ Wait for the reception or transmission of a valid reference message or for TCMR0 match
⎯ If the local time reaches the value of TCMR0 the Init_Watch_Trigger is reached and the
⎯ If the reference message is transmitted (TXACK[30] is set) set RFTROFF to zero
⎯ If a valid reference message is received (RXPR[31] is set) then:
⎯ Disable TCMR0 compare match by clearing bit 10 of TTCR0
⎯ Enable TCMR2 compare match by setting bit 12 of TTCR0
⎯ Only after two reference messages have been detected on the CAN Bus (transmitted or
application needs to set TXCR for Mailbox 30 and start again
• If 3 LSBs of ID of Mailbox 31 have high priority than the 3 LSBs of Mailbox 30 (if
• If 3 LSBs of ID of Mailbox 31 have lower priority than the 3 LSBs of Mailbox 30 (if
received) can the application set TXPR for the other Time Triggered Mailboxes.
• Set RFTROFF to the requested Init_Ref_Offset value
• Set TXPR for Mailbox 30
• Write H'4000 into TTTSEL
working as potential time master) keep RFTROFF to Init_Ref_Offset
working as potential time master) decrement by 1 the value in RFTROFF
