This is an application example where the count value is captured to CR01n, TM0n is cleared, and the TO0n
output is inverted when the rising or falling edge of the TI00n pin is detected.
When the edge of the TI01n pin is detected, an interrupt signal (INTTM00n) is generated. Mask the INTTM00n
signal when it is not used.
Remark n = 0:
