TTW[1:0] (Time Trigger Window):
These bits show the attribute of time windows. Please
note that once a merged arbitrating window is opened by TTW = 2'b10, the window must be
closed by TTW = 2'b11. Several messages with TTW = 2'b10 may be used within the start and
the end of a merged arbitrating window.

The first 16-bit area specifies the time that triggers the transmission of the message in cycle time.
The second 16-bit area specifies the basic cycle in the system matrix where the transmission must
start (Offset) and the frequency for periodic transmission. When the internal TTT register matches
to the CYCTR value, and the internal Offset matches to CCR value transmission is attempted from
the corresponding Mailbox. In order to enable this function, the CMAX (Cycle Maximum
Register) must be set to a value different from 3'b111, the Timer (TCNTR) must be running
(TTCR0 bit15 = 1), the corresponding MBC must be set to 3'b000 and the corresponding TXPR
bit must be set. Once TXPR is set by S/W, RCAN-TL1 does not clear the corresponding TXPR bit
(among Mailbox-30 to 24) to carry on performing the periodic transmission. In order to stop the
periodic transmission, TXPR must be cleared by TXCR. Please note that in this case it is possible
that both TXACK and ABACK are set for the same Mailbox if TXACK is not cleared right after
completion of transmission. Please refer to figure 19.7.
