When the CMMS bit in TCMIER is set to 1, cycle measurement is performed only while the
TCMMCI signal is high (MCICTL in TCMCSR is 0). Figure 11.9 shows an example of timing in
cycle measurement when the CMMS bit is set to 1.

The timer overflow flag can be used to determine the external event (TCMCYI) stopped state.
Either of two sets of conditions represents the external event stopped state.
The external event can be considered to have stopped when a timer overflow is generated within
the period from the start of cycle measurement mode to detection of the first edge (rising or falling
as selected with the IEDG bit in TCMCR).
Figure 11.10 shows an example of the timing of the external event stopped state (1).
