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
Configuration of the Timer Unit
・ The mode timer can be reset by a signal from the position detection circuit, Timer 3, or overload
・ The value of the mode timer during counting can be read by capturing the count in software and reading
・ 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
・ When capturing by position detection is enabled, the capture register has the timer value captured in it
protective circuit. If the mode timer overflows without being reset, it stops at FFFFH and sets an
