(e) Start timing in capture & one-count mode
<1> Operation is enabled (TEn = 1) by writing 1 to the TSn.
<2> Enters the start trigger input wait status, and TCRn holds the initial value.
<3> On start trigger detection, 0000H is loaded to TCRn and count starts.

Note
When the capture & one-count mode is set, the operation clock (fMCK) is selected as count clock
(CCS1n, CCS0n = 0).
Caution An input signal sampling error is generated since operation starts upon start trigger
detection (If the TIn pin input signal is used as a start trigger, an error of one count clock
occurs).
