(2) Precautions to be observed when using TML measure input
The following describes precautions to be observed when using TML measure input.
• If measure event input and write to the counter occur simultaneously in the same clock period,
the write value is set in the counter, whereas the up-count value (before being rewritten) is
latched to the measure register.
• If the timer operates with any clock other than the 1/2 internal peripheral clock while clock bus
1 is selected for the count clock, the counter cannot be written to normally. Therefore, when
operating with any clock other than the 1/2 internal peripheral clock, do not write to the counter.
• If the timer operates with any clock other than the 1/2 internal peripheral clock while clock bus
1 is selected for the count clock, the captured value is one that leads the actual counter value
by one clock period. However, during the 1/2 internal peripheral clock interval from the count
clock, this problem does not occur and the counter value is captured at exact timing.
The diagram below shows the relationship between counter operation and the valid data that can
be captured.
