11.4.1 Configuration of the Timer Unit
controlled by timer control registers and timer compare registers.
The timer unit consists mainly of a mode timer, three timer comparator, and mode capture register, and is
• The mode timer can be reset by a signal from the position detection circuit, Timer 3, or overload pro-
• The value of the mode timer during counting can be read by capturing the count in software and read-
• Timer 1 and Timers 2 and 3 generate an interrupt signal by magnitude comparison and matching com-
• When any one of Timers 1 to 3 interrupts occurs, the next interrupts can be enabled by writing a new
