TM8BC counter counts up. When the TM8BC counter and the TM8CA register match, the condition of the output
pin (TM8AIO) is inverted at the rising edge of the next count clock.
The value of the TM8BC counter is initialized to 0x0000 and starts to count up again.
Timer output cycle = (TMnCA value + 1) × Count clock source cycle × 2
