The CMF flag in TDPCSR is set in the last state in which the values in TDPCNT and TDPWDMX
match (timing when TDPCNT updates the matched count value) in timer mode. Accordingly, a
compare match signal is not generated until an additional cycle of the TDPCNT input clock is
generated after a match between the values in TDPCNT and TDPWDMX. For details, see section
12.6.2, Conflict between TDPPDMX Write and Compare Match. Figure 12.6 shows the timing on
which the CMF flag is set.
12.4.2
The TDP operates in cycle measurement mode when the TDPMDS bit in TDPCR1 is set to 1.

TDPCNT counts up in cycle measurement mode regardless of the setting of the CST bit in
TDPCR1. TDPCNT is cleared to H'0000 when the first edge in the measurement period is
detected, from which state it counts up. Figure 12.7 shows an example of counter operation in
cycle measurement mode.
