2. Set the valid edge of the TI001/P05 pin using prescaler mode register 01 (PRM01).
3. If any the following modes: the mode in which clear & start occurs on match between TM01

and CR001, the mode in which clear & start occurs at the TI01 valid edge, or free-running
mode is selected, when the set value of CR001 is FFFFH and the TM01 value changes from
FFFFH to 0000H, the OVF01 flag is set to 1.
After reset: 00H
