• Description: 8-bit Single-chip Microcontrollers
• Manufacturer: Renesas Electronics Corporation.

(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 ES001, ES000 = 1, 0 and ES101, ES100 = 1, 0 is prohibited.
Falling edge
Rising edge
No capture operation
Falling edge
Rising edge
Both rising and falling edges
Cautions 1. Set a value other than 0000H in CR000 in the mode in which clear & start occurs on a match

CRC001, CRC000: Bits 1 and 0 of capture/compare control register 00 (CRC00)
2. If CR000 is set to 0000H in the free-running mode and in the clear mode using the valid edge
3. When P01 is used as the valid edge input of the TI010 pin, it cannot be used as the timer
4. When CR000 is used as a capture register, read data is undefined if the register read time
5. Do not rewrite CR000 during TM00 operation.

of the TI000 pin, an interrupt request (INTTM000) is generated when the value of CR000
changes from 0000H to 0001H following TM00 overflow (FFFFH). Moreover, INTTM000 is
generated after a match of TM00 and CR000 is detected, a valid edge of the TI010 pin is
detected, and the timer is cleared by a one-shot trigger.

input of the TI010 pin.
and capture trigger input conflict (the capture data itself is the correct value).
If timer count stop and capture trigger input conflict, the captured data is undefined.
