(1) TI00n pin valid edge selected as capture trigger (CRC0n1 = 1, CRC0n0 = 1)
(2) TI01n pin valid edge selected as capture trigger (CRC0n1 = 0, CRC0n0 = 1)
Remarks 1. Setting ES0n1, ES0n0 = 1, 0 and ES1n1, ES1n0 = 1, 0 is prohibited.

2. If CR00n is set to 0000H in the free-running mode and in the clear mode using the valid edge
3. When the valid edge of the TI01n pin is used, P01 or P06 cannot be used as the timer output
4. When CR00n is used as a capture register, read data is undefined if the register read time
5. Do not rewrite CR00n during TM0n operation.

of the TI00n pin, an interrupt request (INTTM00n) is generated when the value of CR00n
changes from 0000H to 0001H following TM0n overflow (FFFFH). Moreover, INTTM00n is
generated after a match of TM0n and CR00n is detected, a valid edge of the TI01n pin is
detected, or the timer is cleared by a one-shot trigger.
(TO0n) pin. Moreover, when the TO0n pin is used, the valid edge of the TI01n pin cannot be
used.

If timer count stop and capture trigger input conflict, the captured data is undefined.
