(1) TI000 pin valid edge selected as capture trigger (CRC001 = 1, CRC000 = 1)
(2) TI010 pin valid edge selected as capture trigger (CRC001 = 0, CRC000 = 1)
Remarks 1. Setting ES010, ES000 = 1, 0 and ES110, ES100 = 1, 0 is prohibited.
Cautions 1. Set CR000 to other than 0000H in the clear & start mode entered on match between TM00

When CR000 is used as a capture register
It is possible to select the valid edge of the TI000 pin or the TI010 pin as the capture trigger. Setting of the
TI000 or TI010 valid edge is performed by means of prescaler mode register 00 (PRM00) (refer to Table 6-
2).

3. The value of CR000 after 16-bit timer/event counter 00 has stopped is not guaranteed.
4. The capture operation may not be performed for CR000 set in compare mode even if a

register is used as an external event counter. However, in the free-running mode and in
the clear & start mode using the valid edge of the TI000 pin, if CR000 is set to 0000H, an
interrupt request (INTTM000) is generated when CR000 changes from 0000H to 0001H
after an overflow (FFFFH).

the value of CR000 is changed.

the input pin (TI010) of the valid edge.
used as a capture register, the capture trigger input takes precedence and the read data
is undefined. Also, if the count stop of the timer and the input of the capture trigger
conflict, the capture trigger is undefined.
