[Precautions when using Timer B2]
• Event Counter Mode
• Pulse Period/Pulse Width Measurement Mode
• Timer mode: The timer counts an internal count source.
• Event counter mode: The timer counts pulses from an external device or overflows or underflows of
• Pulse period/pulse width measuring mode: The timer measures an external signal's pulse period or
• A/D trigger mode: The timer starts counting by one trigger until the count value becomes 0000
