RCAN-TL1 offers a H/W support to perform communication in Time Trigger mode in line with
the emerging ISO-11898-4 Level 1 Specification.
This section reports the basic procedures to use this mode.
• Setting Time Trigger Mode
In order to set up the time trigger mode the following settings need to be used.
• Roles of Registers
The user registers of RCAN-TL1 can be used to handle the main functions requested by the
TTCAN standard.
TCNTR
RFMK
CYCTR
RFTROFF
Mailbox-31
Mailbox-30
Mailbox-29 to 24
Mailbox-23 to 16
Mailbox-15 to 0
Tx-Trigger Time
⎯ CMAX in CMAX_TEW must be programmed to a value different from 3'b111.
⎯ Bit 15 in TTCR0 has to be set, to start TCNTR.
⎯ Bit 6 in TTCR0 has to be cleared to prevent TCNTR from being cleared after a match.
⎯ DART in Mailboxes used for time-triggered transmission cannot be used, since for Time
Time Triggered Transmission
Triggered Mailboxes, TXPR is not cleared to support periodic transmission.
Cycle Time = TCNTR - RFMK
Mailbox dedicated to the reception of time reference message
Ref_Mark
Ref_Trigger_Offset for Mailbox-30
Mailbox dedicated to the transmission of time reference message when
working as a potential time master
Mailboxes supporting time-triggered transmission
Mailboxes supporting reception without timestamp (may also be
implemented as Mailboxes supporting Event Triggered transmission)
Mailboxes supporting reception with timestamp timestamp (may also be
implemented as Mailboxes supporting Event Triggered transmission)
Time_Mark to specify when a message should be transmitted
