16-bit timer × 5
• Timer mode
The timer counts an internal count source.
• Event counter mode
The timer counts pulses from an external device or overflows and underflows of other timers.
• One-shot timer mode
The timer outputs a pulse only once before it reaches the minimum count 0000h.
• Pulse width modulation (PWM) mode
The timer outputs pulses of given width and cycle successively.
• Programmable output mode
The timer outputs a given pulse width of a high-/low- level signal (timers A1, A2, and A4).
