TIO4 operation mode select bit
Note 1: During measure free-run/clear input mode, even if this bit is set to "0" (external input disabled), when a capture signal is
entered from an external device, the counter value at that point in time is written into the measure register. In measure clear
input mode, however, if this bit = "0" (external input disabled), the counter value is not initialized (H'FFFF) upon capture
and, therefore, this bit should be set to "1" (external input enabled) when using measure clear input mode.
Note: • Operation mode can only be set or changed while the counter is inactive.
