Basic Cycle End Entry
The basic cycle end entry defines the time mark value that is used as a watch trigger
time mark. In the case that the TTCAN system is waiting for a reference message while
the system is normally synchronized (not in a gap = not waiting for another event to
synchronize). If the system is in a gap with GM set, the following entries can be read.
The basic cycle end is defined as follows:

Field Bits Type Description
TMV [15:0] rw Time Mark Value
This bit field determines the compare value for the
next time mark that is used for the next compare
action with the cycle time.
TMV determines the watch trigger that is used to
generate a watch trigger event WTE when the cycle
time reaches TMV.
The value written into TMV must meet the condition
that a minimum of one CAN frame length is in
between the last time mark and the basic cycle end
entry. For this calculation, the reference trigger offset
TMR.RTO for the reference message entry must
also be taken into account.
