(CR00n: compare register, CR01n: capture register)
This is an application example where the TO0n output level is inverted when the count value has been captured &
cleared.
The count value is captured to CR01n and TM0n is cleared (to 0000H) when the valid edge of the TI00n pin is
detected. When the count value of TM0n is 0001H, a compare match interrupt signal (INTTM00n) is generated, and
the TO0n output level is inverted.
