• Manufacturer Part Number: upd78f0730
• Description: 8-bit Single-chip Microcontroller
• Manufacturer: Renesas Electronics Corporation.

(4) Operation in clear & start mode entered by TI000 pin valid edge input
TI010 pin
(CR000: capture register, CR010: capture register)
Note The timer output (TO00) cannot be used when detecting the valid edge of the TI010 pin is used.
This is an application example where the count value is captured to CR010, TM00 is cleared, and the TO00 pin
output is inverted when the rising or falling edge of the TI000 pin is detected.
When the edge of the TI010 pin is detected, an interrupt signal (INTTM000) is generated. Mask the INTTM000
signal when it is not used.
