Note 1: To select the TIO3 enable/measure input source, use the TIO4 Control Register's TIO34ENS (TIO3,
TIO4 enable/measure input source selection) bit.
Note 2: 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 to
the measure register. However, because in measure clear input mode, if this bit = 0 (external input
disabled), the counter value is not initialized (H'FFFF) upon capture, we recommend that this bit be
set to 1 (external input enabled) when using measure clear input mode.
Note 3: This register must always be accessed in halfwords.
Note 4: Always make sure the counter has stopped and is idle before setting or changing operation modes.
